Question

Choose all the true statements about oxidative phosphorylation.

Answer 1

Answer:

A. Oxidative phosphorylation occurs in the inner mitochondrial membrane.

B. The oxidation of NADH provides enough energy to produce three ATP molecules.

Explanation:

Oxidative phosphorylation is the third step of cellular respiration, in which NADH2 or FADH electron carriers are oxidized to produce ATP. Oxidative phosphorylation occurs in the inner mitochondrial membrane. It is composed of two processes viz: electron transport chain and chemiosmosis.

Either NADH2 or FADH is used as the starting electron carrier. When NADH is used, its oxidation produces enough energy to generate 3 molecules of ATP per molecule while FADH generates 2 ATP molecules.
