In respiratory electron transport chain cytochrome - b is reduced by:
Correct answer: D. Coenzyme - Q
- A. NADH
- B. FADH
- C. Cytochrome - C
- D. Coenzyme - Q
Explanation
Cytochrome-b is reduced by electrons which are released by the oxidation of coenzyme Q.

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.
