Most of the ATP from aerobic respiration comes from
A.oxidative phosphorylation
B.glycolysis
C.the Krebs cycle
D.fermentation
Explanation
Core Concept
The electron transport chain and chemiosmosis generate the bulk (~26–28) of the roughly 30–32 ATP per glucose; glycolysis and the Krebs cycle contribute only 4 by substrate-level phosphorylation.
Correct Answer
Aoxidative phosphorylation
