During complete aerobic respiration of one glucose molecule, which stage contributes the largest share of ATP?

A.Oxidative phosphorylation
B.Glycolysis
C.Pyruvate oxidation
D.Fermentation

Explanation

Core Concept

Oxidative phosphorylation produces the largest share of ATP during complete aerobic oxidation of glucose. NADH and FADH2 carry electrons from earlier stages to the electron-transport chain, which establishes the proton-motive force used by ATP synthase. The AP-core idea is the dominant contribution of oxidative phosphorylation; an exact universal total such as 30–32 ATP, or 26–28 from this stage, is unnecessary and can vary with cellular conditions.
