Q. During which stage in the complete oxidation of glucose are the greatest number of ATP molecules formed from ADP ?
A) Conversion of pyruvic acid to acetyl Co-A
B) Electron transport chain
C) Glycolysis
D) Krebs cycle
Explanation
[Solution from source] Most of the ATP from aerobic respiration (about 34 of 38 in the older count) is made by oxidative phosphorylation as NADH and FADH₂ pass electrons down the electron transport chain. Glycolysis and the Krebs cycle make only a few ATP directly, by substrate-level phosphorylation. Answer (2).
