Question

The complex concerned with oxidative phosphorylation in inner mitochondrial membrane is:

• A. Complex IV
• B. Complex V
• C. Complex III
• D. Complex II

Answer 1

The correct option is B Complex V

ATP is formed as a result of the transfer of electrons from NADH or $FAD{H}_2$ to $O_2$ by a series of electron carriers in the ETC (electron transport chain), which involve complexes I through IV. Complex V is the ATP synthase, which is the site of the production of ATP or oxidative phosphorylation.
