Complex-I in electron transpo chain is ?: (A) NADH - CoQ reductase, (B) CoQ - cytochrome C reductase, (C) Cytochrome-C oxidase, (D) None of the above
Answer is A. Ans. is 'a' i.e., NADH - CoQ reductase Components of ETC are :?Complex I (NADH - CoQ reductase) catalyzes the transfer of electron from NADH to coenzyme Q (CoQ).Complex II (Succinate - CoQ reductase or succinate dehydrogenase) transfers electrons from succinate to coenzyme Q.Complex III (CoQ - cytochrome C reductase), transfers electron from CoQ to cytochrome C.Complex IV (cytochrome C oxidase) transfers electrons from cytochrome C to 02.
