Which generates the most ATP?
The electron transport chain Explanation: The electron transport chain generates the most ATP out of all three major phases of cellular respiration.
Which process produces the most ATP quizlet?
The glycolysis stage is responsible for producing most of the ATP during cellular respiration.
Which process produces the most ATP aerobic or anaerobic?
Aerobic respiration Aerobic respiration produces much more ATP than anaerobic respiration. Anaerobic respiration occurs more quickly than aerobic respiration.
Does aerobic or anaerobic produce more ATP?
Aerobic respiration produces more ATP than anaerobic respiration due to the complete oxidation of glucose to CO2 and water. O2 acts as the terminal electron acceptor in the electron transport chain and gets reduced to water. Most of the ATPs are produced by oxidative phosphorylation in the electron transport chain.
Which produces more energy aerobic respiration or fermentation?
Aerobic respiration produces more usable chemical energy than fermentation because it involves .
Which process yields more ATP fermentation or anaerobic respiration?
Anaerobic respiration process yields more ATP because the 2 ATP produced by substrate-level phosphorylation is the total energy yield of fermentation. 7.6 – Describe how the catabolic pathways of glycolysis and the critic acid cycle intersect with anabolic pathways in the metabolism.
Which produces more ATP fermentation or aerobic respiration?
Aerobic respiration produces more ATP than anaerobic respiration due to the complete oxidation of glucose to CO2 and water. O2 acts as the terminal electron acceptor in the electron transport chain and gets reduced to water. Most of the ATPs are produced by oxidative phosphorylation in the electron transport chain.
Does glycolysis generate ATP?
Glycolysis produces only two net molecules of ATP per 1 molecule of glucose. However, in cells lacking mitochondria and/or adequate oxygen supply, glycolysis is the sole process by which such cells can produce ATP from glucose.
Which produces more ATP fermentation or cellular respiration?
Cellular respiration produces 38 ATP, while fermentation produces only 2 ATP. 4. Cellular respiration is more efficient than fermentation in the generation of ATP.
Which process creates more ATP aerobic or anaerobic respiration?
Aerobic respiration produces much more ATP than anaerobic respiration. Anaerobic respiration occurs more quickly than aerobic respiration.
Which produces more ATP aerobic or anaerobic?
Aerobic respiration produces more ATP than anaerobic respiration due to the complete oxidation of glucose to CO2 and water. O2 acts as the terminal electron acceptor in the electron transport chain and gets reduced to water. Most of the ATPs are produced by oxidative phosphorylation in the electron transport chain.
Does fermentation or anaerobic respiration produce more ATP?
The most efficient way is through aerobic respiration, which requires oxygen. This method gives the most ATP per energy input.
How many ATP are produced in anaerobic respiration?
2 ATP In anaerobic conditions, there is no conversion of NADH to ATP. There is lactate production in animals and ethanol plus carbon dioxide in plants. Thus, the ATP molecules produced in anaerobic respiration is 2 ATP.
Does gluconeogenesis produce ATP?
Glucose is made from pyruvate in gluconeogenesis at the cost of 4 ATP, 2 GTP, and 2 NADH. The breakdown pathway of glucose in glycolysis yields 2 ATP and 2 NADH.
Does anaerobic or aerobic respiration produce more ATP?
Aerobic Anaerobic cell respiration (glycolysis + fermentation) produces 2 ATP/glucose consumed. Aerobic cell respiration (glycolysis + the Krebs cycle + respiratory electron transport) produces 36 ATP/glucose consumed. Aerobic cell respiration is roughly 18 times more efficient than anaerobic cell respiration.
Does aerobic respiration produce more ATP than fermentation?
Anaerobic cell respiration (glycolysis + fermentation) produces 2 ATP/glucose consumed. Aerobic cell respiration (glycolysis + the Krebs cycle + respiratory electron transport) produces 36 ATP/glucose consumed. Aerobic cell respiration is roughly 18 times more efficient than anaerobic cell respiration.
Why does anaerobic respiration produce more ATP?
The Presence of Oxygen Glycolysis is an anaerobic process – it does not need oxygen to proceed. This process produces a minimal amount of ATP. The Krebs cycle and electron transport do need oxygen to proceed, and in the presence of oxygen, these processes produce much more ATP than glycolysis alone.
How many ATP is produced in glycolysis?
2 ATP During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi –> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O).
Does glycolysis produce ATP?
Glycolysis produces only two net molecules of ATP per 1 molecule of glucose. However, in cells lacking mitochondria and/or adequate oxygen supply, glycolysis is the sole process by which such cells can produce ATP from glucose.
How many ATP are produced in glycogenesis?
two molecules of ATP are used in the synthesis of glycogen from glucose; debranching enzyme releases glucose, then, two molecules of ATP will be used in the preparatory phase of glycolysis; four molecules of ATP are produced in the payoff phase of glycolysis.
Does glycolysis produce more ATP than aerobic respiration?
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.
How many ATP is produced in TCA cycle?
2 ATPs 2 ATPs are produced in the TCA cycle per glucose molecule (2 acetyl CoA). ATP is produced when Succinyl CoA produces succinate by the enzyme succinyl CoA synthetase. It is important to note that most of the ATP produced in cellular respiration account for oxidative phosphorylation in the electron transport chain.
How many ATP are produced in fermentation?
two ATP Fermentation only produces two ATP per glucose molecule through glycolysis, which is much less ATP than cellular respiration.
Which produces more ATP anaerobic or aerobic?
Aerobic respiration produces more ATP than anaerobic respiration due to the complete oxidation of glucose to CO2 and water. O2 acts as the terminal electron acceptor in the electron transport chain and gets reduced to water. Most of the ATPs are produced by oxidative phosphorylation in the electron transport chain.
How many ATP are produced in glycolysis cycle?
During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi –> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O).
How many ATP are produced in glycolysis and TCA cycle?
2 ATPs are produced in the TCA cycle per glucose molecule (2 acetyl CoA). ATP is produced when Succinyl CoA produces succinate by the enzyme succinyl CoA synthetase. It is important to note that most of the ATP produced in cellular respiration account for oxidative phosphorylation in the electron transport chain.
Which process makes more ATP cellular respiration or fermentation?
Although fermentation produces less ATP, it has the advantage of doing so very quickly. It allows your muscles, for example, to get the energy they need for short bursts of intense activity. Aerobic cellular respiration, in contrast, produces ATP more slowly.
How many ATPs are produced in glycolysis and fermentation?
Two ATPs are produced in fermentation, mainly in the glycolysis process. Glucose first converts to pyruvates through glycolysis process and then to lactic acids or alcohol as well as other products of fermentation. In the glycolysis process, 2 pyruvates, 2 net ATP, and 2 NADH are produced.
How many ATP are generated in TCA cycle?
2 ATPs 2 ATPs are produced in the TCA cycle per glucose molecule (2 acetyl CoA). ATP is produced when Succinyl CoA produces succinate by the enzyme succinyl CoA synthetase. It is important to note that most of the ATP produced in cellular respiration account for oxidative phosphorylation in the electron transport chain.
Which stage of cellular respiration produces the most ATP?
electron transport system The stage that produces most of the ATP during cellular respiration is the electron transport system (ETS) present in mitochondria. The formation of ATP occurs by oxidative phosphorylation.
