Correct answer: B. Inner membrane of mitochondrion
- A. Outer membrane of mitochondrion
- B. Inner membrane of mitochondrion
- C. Matrix of mitochondrion
- D. Inner side of thylakoid membrane
Explanation
The molecular mechanism of oxidative phosphorylation takes place in conjunction with the respiratory chain in the mitochondrial inner membrane.The respiratory chain is a series of protein complexes that are embedded in the mitochondrial inner membrane. The respiratory chain uses the energy released from the oxidation of NADH and FADH2 to pump protons across the mitochondrial inner membrane. This creates a proton gradient, which is used to drive the synthesis of ATP.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
