During respiration, Oxidative phosphorylation occurs in

Oxidative phosphorylation is the process of ATP synthesis coupled with the transfer of electrons through the electron transport chain (ETC) to oxygen.

The complexes of the electron transport chain and the enzyme ATP synthase, which are responsible for oxidative phosphorylation, are embedded in the inner mitochondrial membrane.

Glycolysis occurs in the cytoplasm, while the Krebs cycle takes place in the mitochondrial matrix.

Answer: Inner Mitochondrial membrane only
