Question

Which of the following complexes regarding oxidative phosphorylation in respiration, catalyse the production of ATP from ADP and inorganic phosphate?

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

Answer 1

The correct option is A Complex V

A.Complex V – it is also called ATP synthase. It involves in the formation of ATP.

B.Complex II – It is also called Succinic FAD oxidoreductase. It is involved in the oxidation of FADH₂.

C. Complex – IV – It is also called cytochrome C oxidase. It is involved in the transfer electrons to nacent oxygen.

D.Complex – III – It is also called Cytochrome C reductase. It is involved in the transfer of electrons to cytochrome C.

So, the correct option is ‘Complex V’.
