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)
