During respiration, Oxidative phosphorylation occurs in
Options
- ACytoplasm only
- BMitochondrial matrix only
- CInner Mitochondrial membrane only
- DInter membrane space of Mitochondria
Correct answer
C. Inner Mitochondrial membrane only
Step-by-step solution
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
