38 ATP molecules can theoretically be produced in aerobic conditions from one glucose molecule in glycolysis, Krebs cycle and electron transport system.
How many ATP molecules can theoretically be produced from the NADH generated by the catabolism?
Theoretically ATP yield for every oxidation cycle can be maximum upto 17, as NADH produces 3 ATP , FADH2 = 2 and end product, acetyl COA governed Citric Acid Cycle produces 12 ATP.
How many ATP molecules are theoretically produced by a molecule of glucose?
In eukaryotic cells, the theoretical maximum yield of ATP generated per glucose is 36 to 38 , depending on how the 2 NADH generated in the cytoplasm during glycolysis enter the mitochondria and whether the resulting yield is 2 or 3 ATP per NADH.
How many ATP molecules are ideally produced?
Ideally, how many ATP molecules are produced from one glucose molecule in cellular respiration? Explanation: A total of 38 ATP molecules are produced from one molecule of glucose. 2 ATP from glycolysis, 2 ATP from the Krebs cycle, and about 34 ATP from the electron transport chain.
What is the maximum number of ATP molecules that are produced?
The maximum number of ATP molecules that can be produced during aerobic respiration is 38 .
Is it 36 or 38 ATP?
According to some newer sources, the ATP yield during aerobic respiration is not 36–38 , but only about 30–32 ATP molecules / 1 molecule of glucose, because: ATP : NADH+H + and ATP : FADH 2 ratios during the oxidative phosphorylation appear to be not 3 and 2, but 2.5 and 1.5 respectively.
How many ATP are produced from 1 NADH?
Moreover, it is general believed that 4 H+ are demanded for the synthesis of 1 ATP. Consequently, 2.5 ATP per NADH are formed.
Why do eukaryotes only produce 36 ATP?
Why do eukaryotes generate only about 36 ATP per glucose in aerobic respiration but prokaryotes may generate about 38 ATP? A) eukaryotes have a less efficient electron transport system. ... eukaryotes do not transport as much hydrogen across the mitochondrial membrane as prokaryotes do across the cytoplasmic membrane.
What is the net ATP gain from one glucose?
The net ATP gain from one glucose molecule in aerobic respiration is 38 ATP . It includes ATP produced in glycolysis, link reaction
How many ATP are produced in fermentation?
Organisms carrying out fermentation, called fermenters, produce a maximum of two ATP molecules per glucose during glycolysis.
How is 34 ATP produced?
The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO 2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). ... This stage converts the NADH into ATP.
Why the number of ATP is not known exactly?
The total number of ATP is not known exactly and is due to variance in the degree of coupling between the flow of protons through the ATPase and electron transport . ATP – Adenosine triphosphate, the energy currency of the cell are organic compounds composed of the phosphate groups, adenine and sugar ribose.
How many molecules of ATP are obtained from each NADH2?
Since 1 NADH2 = 3 ATP and 1 FADH2 = 2 ATP, total ATP formed are 34.
Why is the total count about 36 or 38?
Why is the total count about 36 or 38 ATP molecules rather than a specific number? Since phosphorylation and the redox reactions aren’t directly coupled to each other, the ratio of the number of NADH molecules to the number of ATP molecules is not a whole number .
Where is 36 ATP produced?
During respiration, 36 ATP molecules are produced per glucose molecule. 2 molecules of ATP are produced outside mitochondria i.e., during glycolysis and other 34 molecules of ATP are produced inside mitochondria from Krebs cycle.
