Question

most of the atp made during cellular respiration is generated by ____________. fermentation glycolysis substrate - level phosphorylation pyruvate oxidation oxidative phosphorylation i dont know yet

Explanation:

• Fermentation is an anaerobic process and does not produce a large amount of ATP compared to aerobic cellular respiration.
• Glycolysis produces a small amount of ATP (net gain of 2 ATP per glucose molecule).
• Substrate - level phosphorylation occurs in glycolysis and the citric acid cycle but only contributes a small portion of the total ATP.
• Pyruvate oxidation does not directly produce ATP.
• Oxidative phosphorylation, which occurs in the electron transport chain and chemiosmosis, produces the majority of ATP (about 28 - 32 ATP per glucose molecule in aerobic respiration) through the flow of electrons and the establishment of a proton gradient.

Answer:

oxidative phosphorylation
