Q. No.The chemiosmotic coupling hypothesis of oxidative phosphorylation proposes that Adenosine Triphosphate (ATP) is formed because:
| 1. | high energy bonds are formed in mitochondrial proteins |
| 2. | ADP is pumped out of the matrix into the inter-membrane space |
| 3. | a proton gradient forms across the inner membrane |
| 4. | there is a change in the permeability of the inner mitochondrial membrane toward Adenosine Diphosphate (ADP) |
