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 intermembrane 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)

Oxidative phosphorylation is

1. formation of ATP by transfer of phosphate group from a substrate to ADP
2. oxidation of phosphate group in ATP
3. addition of phosphate group to ATP
4. formation of ATP by energy release from electrons removed during substrate oxidation.
