Question

Consider the following statements w.r.t. respiration
a. Cyt-b is a mobile electron carrier
b. $C{O}_2$ is end product of all types of respiration
c. Five atoms of oxygen are required for complete oxidation of one molecule of pyruvate
d. Conversion of succinate to fumarate produces a reduced coenzyme.

• A. a & c are incorrect
• B. Only d is correct
• C. a & d are correct
• D. b & d are correct

Answer 1

The correct option is A a & c are incorrect

Cyt-b is part of ETS which act as an electron carrier and formation of ATP whereas CO${}_2$ is the only end product of anaerobic respiration. conversion from succinate to fumarate produces a reduced coenzyme known as succinate dehydrogenase (SDH) or succinate-coenzyme Q reductase (SQR).

So the correct option is 'a & c are incorrect'
