Question

The chemiosmotic coupling hypothesis of oxidative phosphorylation proposes that adenosine triphosphate (ATP) is formed because

• A. There is a change in the permeability of the inner mitochondrial membrane toward adenosine diphosphate (ADP)
• B. High energy bonds are formed in mitochondrial proteins
• C. ADP is pumped out of the matrix into the intermembrane space
• D. A proton gradient forms across the inner membrane

Answer 1

The correct option is D A proton gradient forms across the inner membrane

Proton motive force develops between perimitochondrial space and matrix across inner mitochondrial membrane.
