in glycolysis 2 atp produce ____ atp ____ oxygen

This process produces a minimal amount of ATP. Glycolysis produces 2 NADH, 2 ATP, and 2 pyruvate molecules per molecule of glucose. Glucose + 2 ADP + 2 Pi + 2 NAD + → 2 pyruvate + 2 ATP + 2 NADH + 2 H + + 2 H 2 O Metabolism of glycolysis end products in the Krebs cycle produces much larger amounts of ATP than glycolysis does. So far, glycolysis has cost the cell two ATP molecules and produced two small, three-carbon sugar molecules. 1 ATP, 3 NADPH, and 1 FADH2 2 ATPs and 2 NADPH* 3 NADPH and 1 FADH2 4 ATPs, 6 NADPH, and 2 FADH2 What are the functions of the high-energy electrons in the electron transport chain? A carbonyl group on the 1,3-bisphosphoglycerate is oxidized to a carboxyl group, and 3-phosphoglycerate is formed. Thus at the end of GLYCOLYSIS, one glucose mocule has generated. Glycolysis - produces lactic acid if process is anaerobic 2. The second half of glycolysis involves phosphorylation without ATP investment (step 6) and produces two NADH and four ATP molecules per glucose. 2 pyruvate molecules (to the LINK REACTION) 2 ATP molecules (2 input, 4 output) 2 red NAD molecules (to OXIDATIVE PHOSPHORYLATION) NO CO 2 is produced by glycolysis Atom balance is maintained by the two phosphate (P i) groups: Each exists in the form of a hydrogen phosphate anion (HPO 4 2−), … * They hold water bonds. Determine the amount of ATP produced by the oxidation of glucose in the presence and absence of oxygen. In an environment without oxygen, an alternate pathway (fermentation) can provide the oxidation of … then you must include on every digital page view the following attribution: Use the information below to generate a citation. Krebs cycle - produces citric acid 3. Steps Involved in Glycolysis. 1 ATP, 3 NADPH, and 1 FADH2 2 ATPs and 2 NADPH* 3 NADPH and 1 FADH2 4 ATPs, 6 NADPH, and 2 FADH2 What are the functions of the high-energy electrons in the electron transport chain? Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. (This is an example of substrate-level phosphorylation.) 1. glycolysis produces the most ATP in respiration 2. (Note: two ATP molecules are used in the first half of the pathway to prepare the six-carbon ring for cleavage, so the cell has a net gain of two ATP molecules and two NADH molecules for its use). The sixth step in glycolysis (Figure 7.7) oxidizes the sugar (glyceraldehyde-3-phosphate), extracting high-energy electrons, which are picked up by the electron carrier NAD+, producing NADH. For the glycolysis to work, it needs two ATP molecules and then in the end it generates four ATP molecules, so two it gains two more ATP molecules. Glycolysis (see “Glycolysis” concept) is an anaerobic process – it does not need oxygen to proceed. There are 10 enzymes involved in breaking down sugar. ATP is formed in the presence of oxygen in the process known as aerobic cellular respiration. are licensed under a, Atoms, Isotopes, Ions, and Molecules: The Building Blocks, Connections between Cells and Cellular Activities, Structure and Function of Plasma Membranes, Potential, Kinetic, Free, and Activation Energy, Oxidation of Pyruvate and the Citric Acid Cycle, Connections of Carbohydrate, Protein, and Lipid Metabolic Pathways, The Light-Dependent Reactions of Photosynthesis, Using Light Energy to Make Organic Molecules, Signaling Molecules and Cellular Receptors, Mendel’s Experiments and the Laws of Probability, Eukaryotic Post-transcriptional Gene Regulation, Eukaryotic Translational and Post-translational Gene Regulation, Viral Evolution, Morphology, and Classification, Prevention and Treatment of Viral Infections, Other Acellular Entities: Prions and Viroids, Structure of Prokaryotes: Bacteria and Archaea, The Evolutionary History of the Animal Kingdom, Superphylum Lophotrochozoa: Flatworms, Rotifers, and Nemerteans, Superphylum Lophotrochozoa: Molluscs and Annelids, Superphylum Ecdysozoa: Nematodes and Tardigrades, Animal Nutrition and the Digestive System, Transport of Gases in Human Bodily Fluids, Hormonal Control of Osmoregulatory Functions, Human Reproductive Anatomy and Gametogenesis, Fertilization and Early Embryonic Development, Climate and the Effects of Global Climate Change, Environmental Limits to Population Growth, Behavioral Biology: Proximate and Ultimate Causes of Behavior, The Importance of Biodiversity to Human Life. …, Step 4- Cleavage of fructose 1, 6-diphosphate. Glycolysis (see “Glycolysis” concept) is an anaerobic process – it does not need oxygen to proceed. Phase 1: Glycolysis. Krebs cycle produces lactic acid if process is anaerobic 3. electron transport chain produces citric acid Weegy: 1. The ten steps of glycolysis occur in the following sequence: The investment phase is where energy as ATP is put in, and the payoff phase is where net ATP and NADH molecules are created. Step 9. 2 pyruvate molecules (to the LINK REACTION) 2 ATP molecules (2 input, 4 output) 2 red NAD molecules (to OXIDATIVE PHOSPHORYLATION) NO CO 2 is produced by glycolysis Glycolysis - produces lactic acid if process is anaerobic 2. As glycolysis proceeds, energy is released, and the energy is used to make four molecules of ATP. In stage II of catabolism, the metabolic pathway known as glycolysis converts glucose into two molecules of pyruvate (a three-carbon compound with three carbon atoms) with the corresponding production of adenosine triphosphate (ATP). Glycolysis produces 2 NADH, 2 ATP, and 2 pyruvate molecules per molecule of glucose. Glucose enters heterotrophic cells in two ways. In the absence of oxygen, the Krebs cycle is not active and acid and pyruvate can quickly accumulate. This reaction prevents the phosphorylated glucose molecule from continuing to interact with the GLUT proteins, and it can no longer leave the cell because the negatively charged phosphate will not allow it to cross the hydrophobic interior of the plasma membrane. The second part of glycolysis extracts energy from the molecules and stores it in the form of ATP and NADH—remember: this is the reduced form of NAD. Step 1. 4.0 and you must attribute OpenStax. In this situation, the entire glycolysis pathway will proceed, but only two ATP molecules will be made in the second half. Fermentation is less efficient at using the energy from glucose: only 2 ATP are produced per glucose, compared to the 38 ATP per glucose nominally produced by aerobic respiration. The third step is the phosphorylation of fructose-6-phosphate, catalyzed by the enzyme phosphofructokinase. In glycolysis, glucose is converted into pyruvate. Glycolysis begins with the six-carbon ring-shaped structure of a single glucose molecule and ends with two molecules of a three-carbon sugar called pyruvate. If glycolysis is interrupted, these cells lose their ability to maintain their sodium-potassium pumps, and eventually, they die. 1. glycolysis produces the most ATP in respiration 2. Glycolysis is the process of breaking down glucose. What does glycolysis produce for each glucose molecule? Question: Glycolysis A) Uses 2 ATP, Produces 4 ATP, Without Oxygen B) Uses 2 ATP, Produces 4 ATP And Requires Oxygen C) Uses 2 ATP, Produces 2 ATP And Requires Oxygen . Phase 2: Pyruvate oxidation. This enzyme causes 2-phosphoglycerate to lose water from its structure; this is a dehydration reaction, resulting in the formation of a double bond that increases the potential energy in the remaining phosphate bond and produces phosphoenolpyruvate (PEP). They create ATP synthase. The glycolytic pathway is a major metabolic pathway for microbial fermentation … In stage II of catabolism, the metabolic pathway known as glycolysis converts glucose into two molecules of pyruvate (a three-carbon compound with three carbon atoms) with the corresponding production of adenosine triphosphate (ATP). In glycolysis, a molecule of glucose is degraded in a series of enzyme … As a result, there is a net gain of two ATP molecules during glycolysis. 2 ATP are invested and 4 ATP are harvested to produce a net gain of 2 ATP Decide whether the following statements concerning glycolysis are true or false. They make ATP from ADP. One method is through secondary active transport in which the transport takes place against the glucose concentration gradient. The energy to split glucose is provided by two molecules of ATP. Net ATP gain in glycolysis : 2 The ATP are formed by phosphorylation *Phosphorylation – The addition of a phosphate group to a molecule The type of phosphorylation in glycolysis is Substrate level phosphorylation *Substrate level phosphorylation – ATP formation by transferring, via an enzyme, a phosphate group to ADP. Question: Glycolysis A) Uses 2 ATP, Produces 4 ATP, Without Oxygen B) Uses 2 ATP, Produces 4 ATP And Requires Oxygen C) Uses 2 ATP, Produces 2 ATP And Requires Oxygen . So, in glycolysis (which is SLP, so does not depend on oxygen), you create 2 net ATP, directly. The sugar is then phosphorylated by the addition of a second phosphate group, producing 1,3-bisphosphoglycerate. NADH must be reoxidized to NAD + to allow glycolysis to proceed. Step 7. Anaerobic glycolysis is only an effective means of energy production during short, intense exercise, providing energy for a period ranging from 10 seconds to 2 minutes. In the seventh step, catalyzed by phosphoglycerate kinase (an enzyme named for the reverse reaction), 1,3-bisphosphoglycerate donates a high-energy phosphate to ADP, forming one molecule of ATP. Cellular respiration occurs in four phases, that will be discussed in detail below. The Krebs cycle and electron transport do need oxygen to proceed, and in the presence of oxygen, these process produce much more ATP than glycolysis alone.6 мая 2020 г. Outcomes of Glycolysis Glycolysis begins with glucose and produces two pyruvate molecules, four new ATP molecules, and two molecules of NADH. Hexokinase phosphorylates glucose using ATP as the source of the phosphate, producing glucose-6-phosphate, a more reactive form of glucose. The Krebs cycle and electron transport do need oxygen to proceed, and in the presence of oxygen, these process produce much more ATP than glycolysis … The process does not use oxygen directly and therefore is termed anaerobic. (This change from phosphoglucose to phosphofructose allows the eventual split of the sugar into two three-carbon molecules.). The products of GLYCOLYSIS are 2 atp, 2 nadh, and 2 pyruvic acid molecules. Milo is analyzing the steps of cellular respiration. Figure 9.1.2: The second half of glycolysis involves phosphorylation without ATP investment (step 6) and produces two NADH and four ATP molecules per glucose. Our mission is to improve educational access and learning for everyone. Step 3. It occurs in liver cells, and will only phosphorylate the glucose entering the cell to form glucose-6-phosphate (G6P), when the sugar in the blood is abundant. His goal is to quantify the amount of useful chemical energy that cellular respiration can generate from one molecule of glucose. The overall reaction can be expressed this way: Glucose + 2 NAD + + 2 P i + 2 ADP → 2 pyruvate + 2 NADH + 2 ATP + 2 H + + 2 H 2 O + heat An isomerase is an enzyme that catalyzes the conversion of a molecule into one of its isomers. During the pay-off phase of glycolysis, four phosphate groups are transferred to ADP by substrate-level phosphorylation to make four ATP, and two NADH are produced when the pyruvate are oxidized. This process produces a minimal amount of ATP. Both of these molecules will proceed through the second half of the pathway, and sufficient energy will be extracted to pay back the two ATP molecules used as an initial investment and produce a profit for the cell of two additional ATP molecules and two even higher-energy NADH molecules. Step 5- Isomerization of dihydroxyacetone phosphate. The continuation of the reaction depends upon the availability of the oxidized form of the electron carrier, NAD+. The second half of glycolysis involves phosphorylation without ATP investment (step 6) and produces two NADH and four ATP molecules per glucose. Your email address will not be published. The fourth step in glycolysis employs an enzyme, aldolase, to cleave fructose-1,6-bisphosphate into two three-carbon isomers: dihydroxyacetone phosphate and glyceraldehyde-3-phosphate. … The steps with which new ATP are created is called substrate-level phosphorylation. 2 ATP Krebs cycle produces lactic acid if process is anaerobic 3. electron transport chain produces citric acid Weegy: 1. … Contrastand compare substrate-level phosphorylation versus oxidative phosphorylation. Glycolysis can take place with or without oxygen. Aerobic glycolysis occurs in 2 steps. This book is Creative Commons Attribution License The use of symbols in this equation makes it appear unbalanced with respect to oxygen atoms, hydrogen atoms, and charges. As an Amazon Associate we earn from qualifying purchases. Step 2. It also produces two pyruvate molecules and two NADH, the pyruvate molecules are molecules that are rich in carbon and the NADH is a high energy molecule used to produce more ATP. citation tool such as, Authors: Mary Ann Clark, Matthew Douglas, Jung Choi. ATP, Without Oxygen E) None Of The Choices Are Correct Note that the second phosphate group does not require another ATP molecule. The first step in glycolysis (Figure 7.6) is catalyzed by hexokinase, an enzyme with broad specificity … https://openstax.org/books/biology-2e/pages/1-introduction, https://openstax.org/books/biology-2e/pages/7-2-glycolysis, Creative Commons Attribution 4.0 International License, Describe the overall result in terms of molecules produced during the chemical breakdown of glucose by glycolysis, Compare the output of glycolysis in terms of ATP molecules and NADH molecules produced. ATP can be produced by a number of distinct cellular processes; the three main pathways in eukaryotes are (1) glycolysis, (2) the citric acid cycle/oxidative phosphorylation, and (3) beta-oxidation. If NAD+ is not available, the second half of glycolysis slows down or stops. Overall, the process of glycolysis produces a net gain of two pyruvate molecules, two ATP molecules, and two NADH molecules for the cell to use for energy. Step 6. -Electrons removed are delivered to NAD+ producing NADH Process produces 32-34 ATP or 90% of the ATP in the body. Then, unstable fructose-1,6-bisphosphate splits in two, forming two three-carbon molecules called DHAP and glyceraldehyde-3-phosphae. Glycolysis takes place in the cytoplasm. not be reproduced without the prior and express written consent of Rice University. In this phase, there are 2 phosphates added to glucose. Step 10. The enzyme catalyzing this step is a mutase (isomerase). The ATP generated in this process is made by substrate-level phosphorylation, which does not require oxygen. In an environment without oxygen, an alternate pathway (fermentation) can provide the oxidation of NADH to NAD+. Glycolysis begins with glucose and produces two pyruvate molecules, four new ATP molecules, and two molecules of NADH. OXIDATIVE PHOSPHORYLATION CHM01 – General Chemistry 2 26 It composed of Electron Transport Chain and Chemiosmosis. Want to cite, share, or modify this book? Figure 9.1.2: The second half of glycolysis involves phosphorylation without ATP investment (step 6) and produces two NADH and four ATP molecules per glucose. Glycolysis is a vital stage in respiration, as it is the first stage glucose is modified to produce compounds which can go on to be used in the later stages, in addition to generating ATP which can be directly used by the cell. The sixth step in glycolysis (Figure 3) oxidizes the sugar (glyceraldehyde-3-phosphate), extracting high-energy electrons, which are picked up by the electron carrier NAD +, producing NADH. glycolysis begins glucose metabolism, and in the absence of oxygen, lactic acid fermentation takes over. …, Step 3- Phosphorylation of fructose-6-phosphate. Step 4. Thus, 2 pyruvate molecules and 2 ATP molecules are produced from each glucose molecule. If oxygen is available in the system, the NADH will be oxidized readily, though indirectly, and the high-energy electrons from the hydrogen released in this process will be used to produce ATP. Textbook content produced by OpenStax is licensed under a Glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, produces energy in the form of ATP, NADH, and pyruvate, which itself enters the citric acid cycle to produce more energy. They hold water bonds. The overall reaction for glycolysis is: glucose (6C) + 2 NAD+ 2 ADP +2 inorganic phosphates (Pi) yields 2 pyruvate (3C) + 2 NADH + 2 H+ + 2 net ATP. d -Glucose + 2 [NAD] + + 2 [ADP] + 2 [P] i 2 × Pyruvate 2 × + 2 [NADH] + 2 H + + 2 [ATP] + 2 H 2 O Glycolysis pathway overview. Creative Commons Attribution License 4.0 license. Glucose is first converted to fructose-1,6-bisphosphate in a series of steps that use up two ATP. Glycolysis takes place in the cytoplasm of both prokaryotic and eukaryotic cells. t Either cellular respiration or fermentation can be used to release energy, depending on the presence of CARBOHYDRATES. This process alone generates 2 molecules of ATP. Note that the second phosphate group does not require another ATP molecule. Many enzymes in enzymatic pathways are named for the reverse reactions, since the enzyme can catalyze both forward and reverse reactions (these may have been described initially by the reverse reaction that takes place in vitro, under nonphysiological conditions). D) Uses 2 ATP, Produces? Atom balance is maintained by the two phosphate (P i) groups: Each exists in the form of a hydrogen phosphate anion (HPO 4 2−), … A second ATP molecule donates a high-energy phosphate to fructose-6-phosphate, producing fructose-1,6-bisphosphate. Required fields are marked *. In the fifth step, an isomerase transforms the dihydroxyacetone-phosphate into its isomer, glyceraldehyde-3-phosphate. They carry NADPH and FADH2. In this article, we will look at the steps of glycolysis, its relation to other pathways and clinical conditions related to glycolysis. However, under anaerobic conditions, only 2 mol of ATP can be produced. Step 8. Glycolysis will yield a net of 2 ATP. The first step in glycolysis (Figure 7.6) is catalyzed by hexokinase, an enzyme with broad specificity that catalyzes the phosphorylation of six-carbon sugars. Step 5. They create ATP synthase. Thus, pyruvate kinase is a rate-limiting enzyme for glycolysis. The use of symbols in this equation makes it appear unbalanced with respect to oxygen atoms, hydrogen atoms, and charges. The enzyme hexokinase phosphorylates or adds a phosphate group to glucose in a cell's cytoplasm. Following the 10 step sequence of reactions in glycolysis, the energy initially stored in glucose in transferred into ATP, NADH and finally, pyruvate. If the oxygen is present, the pyruvate enters into the citric cycle and electron transport chain and produce more ATPs. The OpenStax name, OpenStax logo, OpenStax book Mature mammalian red blood cells do not have mitochondria and thus are not capable of aerobic respiration—the process in which organisms convert energy in the presence of oxygen—and glycolysis is their sole source of ATP. This is a type of end product inhibition, since ATP is the end product of glucose catabolism. The first step in glycolysis ((Figure)) is catalyzed by hexokinase, an enzyme with broad specificity … © 1999-2021, Rice University. Q. They make ATP from ADP. Step 2- Isomerization of Glucose-6-phosphate. then you must include on every physical page the following attribution: If you are redistributing all or part of this book in a digital format, If oxygen is available in the system, the NADH will be oxidized readily, though indirectly, and the high-energy electrons from the hydrogen released in this process will be used to produce ATP. At this point in the pathway, there is a net investment of energy from two ATP molecules in the breakdown of one glucose molecule. It occurs in inner mitochondrial membrane. Explain why the energy investment phase of Glycolysis is necessary.It is because in this phase that energy is used to break down the glucose molecule to increase the energy after the molecule is phosphorylate. Enolase catalyzes the ninth step. This takes place in the cytoplasm. We recommend using a We breathe air and extract oxygen from it in order to break down glucose (and other nutrients) and produce ATP. -Glycolysis (Takes place in the cytosol) (reaction that happens when very little oxygen is available and produces very little ATP) -Glucose (6 carbons) is oxidized into two molecules of pyruvate (3 carbons each). OpenStax is part of Rice University, which is a 501(c)(3) nonprofit. This is much faster than aerobic metabolism. D) Uses 2 ATP, Produces? Step 6. Your email address will not be published. They carry NADPH and FADH2. In this pathway, phosphofructokinase is a rate-limiting enzyme. glycolysis and krebs cycle What type of phosphorylation makes the ATP in glycolysis and krebs cycle? ATP can be produced by a number of distinct cellular processes; the three main pathways in eukaryotes are (1) glycolysis, (2) the citric acid cycle/oxidative phosphorylation, and (3) beta-oxidation. Glycolysis consists of two distinct phases. ATP by OXIDATIVE PHOSPHORYLATION; 2GPs are converted into two PYRUVATE molecules releasing energy (2 x ATP). ATP, Without Oxygen E) None Of The Choices Are Correct In the eighth step, the remaining phosphate group in 3-phosphoglycerate moves from the third carbon to the second carbon, producing 2-phosphoglycerate (an isomer of 3-phosphoglycerate). * The last step in glycolysis is catalyzed by the enzyme pyruvate kinase (the enzyme in this case is named for the reverse reaction of pyruvate’s conversion into PEP) and results in the production of a second ATP molecule by substrate-level phosphorylation and the compound pyruvic acid (or its salt form, pyruvate). These energy carriers join the 2 ATP and 2 NADH produced in glycolysis and the 2 NADH produced in the conversion of 2 pyruvates to 2 Acetyl CoA. ATP by OXIDATIVE PHOSPHORYLATION; 2GPs are converted into two PYRUVATE molecules releasing energy (2 x ATP). In the second step of glycolysis, an isomerase converts glucose-6-phosphate into one of its isomers, fructose-6-phosphate (this isomer has a phosphate attached at the location of the sixth carbon of the ring). The sugar is then phosphorylated by the addition of a second phosphate group, producing 1,3-bisphosphoglycerate. Thus, the pathway will continue with two molecules of a glyceraldehyde-3-phosphate. Energy investment phase. At the conclusion of the Krebs Cycle, glucose is completely broken down, yet only four ATP have been produced. For the glycolysis to work, it needs two ATP molecules and then in the end it generates four ATP molecules, so two it gains two more ATP molecules. Glucose is a six- memebered ring molecule found in the blood and is usually a result of the breakdown of carbohydrates into sugars. Thus at the end of GLYCOLYSIS, one glucose mocule has generated. The last step in glycolysis will not occur if pyruvate kinase, the enzyme that catalyzes the formation of pyruvate, is not available in sufficient quantities. NADH must be reoxidized to NAD + to allow glycolysis to proceed. When we exhale, we release the CO 2 that is the byproduct of glucose breakdown. Electron transport chain-produces the most ATP in respiration Score 1 The first half of glycolysis uses two ATP molecules in the phosphorylation of glucose, which is then split into two three-carbon molecules. d -Glucose + 2 [NAD] + + 2 [ADP] + 2 [P] i 2 × Pyruvate 2 × + 2 [NADH] + 2 H + + 2 [ATP] + 2 H 2 O Glycolysis pathway overview. Thus, if there is “sufficient” ATP in the system, the pathway slows down. These energy carriers join the 2 ATP and 2 NADH produced in glycolysis and the 2 NADH produced in the conversion of 2 pyruvates to 2 Acetyl CoA. The newly added high-energy phosphates further destabilize fructose-1,6-bisphosphate. In fact, nearly all living organisms carry out glycolysis as part of their metabolism. (Actually, you use 2 ATP, but you make 4, for a NET of 2 ATP). Phosphorylation along the way aids in the process of creating these forms of energy. Here again is a potential limiting factor for this pathway. Note that the second phosphate group does not require another ATP molecule. Thus, NADH must be continuously oxidized back into NAD+ in order to keep this step going. If the cell cannot catabolize the pyruvate molecules further, it will harvest only two ATP molecules from one molecule of glucose. The first occurs in the cytosol and involves the conversion of glucose to pyruvate with resultant production of NADH. In the absence of oxygen, the net yield of ATP produced is 2 per glucose molecule. By the end of this section, you will be able to do the following: As you have read, nearly all of the energy used by living cells comes to them in the bonds of the sugar glucose. At the conclusion of the Krebs Cycle, glucose is completely broken down, yet only four ATP have been produced. Gain a better understanding of the breakdown of glucose by glycolysis by visiting this site to see the process in action. The first part of the glycolysis pathway traps the glucose molecule in the cell and uses energy to modify it so that the six-carbon sugar molecule can be split evenly into the two three-carbon molecules. Glycolysis produces two molecules of pyruvate, two molecules of ATP, two molecules of NADH, and two molecules of water. Glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, produces energy in the form of ATP, NADH, and pyruvate, which itself enters the citric acid cycle to produce more energy. Anaerobic glycolysis is the transformation of glucose to lactate when limited amounts of oxygen (O 2) are available. Investment Phase. This part of the process of cellular respiration is where all the glucose is broken down and turned into two, three carbon molecules called pyruvate molecules. … Glycolysis produces only 2 ATP molecules, but somewhere between 30 and 36 ATPs are produced by the oxidative phosphorylation of the 10 NADH and 2 succinate molecules made by converting one molecule of glucose to carbon dioxide and water, while each cycle of beta oxidation of a fatty acid yields about 14 ATPs.
