Question

What distinguishes mitochondrial ATP production from that in glycolysis?
Options
A It doesn’t require enzymes
B Involves oxidative phosphorylation, not substrate-level phosphorylation
Correct Answer
C Happens in cytoplasm
D Does not use oxygen
Correct Answer

Option B is the correct answer.

Detailed Explanation

Glycolysis produces a small amount of ATP via substrate-level phosphorylation (direct enzyme-coupled transfer of a phosphate group to ADP). The vast majority of ATP from glucose is made in mitochondria via oxidative phosphorylation, which is powered by an electron transport chain and chemiosmosis.

Hint

Different mechanisms in different locations.
