Detailed explanation-1: -Oxidative phosphorylation is the process where energy is harnessed through a series of protein complexes embedded in the inner-membrane of mitochondria (called the electron transport chain and ATP synthase) to create ATP.

Detailed explanation-2: -In the mitochondria’s inner membrane oxidative phosphorylation takes place. The intermembrane gap and the mitochondrial matrix are where the proton gradient is produced.

Detailed explanation-3: -The inner mitochondrial membrane contains many copies of a protein called the F0F1ATPase. This is also called ATP synthase. It consists of two parts: the F0 component spans the membrane and provides a channel for protons to move into the matrix from the intermembrane space.

Detailed explanation-4: -So, the correct answer is ‘ATP-synthetase, succinate dehydrogenase and respiratory chain enzymes’.
