How many net molecules of ATP are made in aerobic cellular respiration through substrate level phosphorylation?
|
|
2 molecules of ATP
|
|
|
4 molecules of ATP
|
|
|
30-32 molecules of ATP
|
|
|
6 molecules of ATP
|
|
|
26-28 molecules of ATP
|
Explanation:
Detailed explanation-1: -Final answer: 6 ATP are formed through substrate-level phosphorylation from one molecule of glucose when it is completely oxidized.
Detailed explanation-2: -Two ATP molecules are required to start glycolysis (from glucose), and four are generated by substrate-level phosphorylation.
Detailed explanation-3: -In aerobic respiration, the full oxidation of one glucose molecule can theoretically yield 38 ATP molecules.
Detailed explanation-4: -In aerobic conditions, pyruvate enters the citric acid cycle and undergoes oxidative phosphorylation leading to the net production of 32 ATP molecules.
Detailed explanation-5: -38 ATP: 4 from substrate-level phosphorylation; 34 from oxidative phosphorylation.
