Question

The chemiosmotic coupling hypothesis of oxidative phosphorylation proposes formation of ATP because

• A. A proton gradient develops across inner membrane
• B. There is change in permeability of inner mitochondrial membrane towards ADP.
• C. High energy bonds are formed in mitochondrial proteins
• D. ADP is pumped out from matrix into inter membrane space.

Answer 1

The correct option is A A proton gradient develops across inner membrane

The chemiosmotic coupling hypothesis of oxidative phosphorylation proposes formation of ATP because of proton gradient.
