During respirartory chain of cellular respiration, cytochrome c oxidizes:
Correct answer: B. Cytochrome b
- A. Cytochrome a
- B. Cytochrome b
- C. Cytochrome a3
- D. Cytochrome a complex
Explanation
In electron- transport chain electrons moves through proteins named as electron carriers. Coenzyme Q reduces cytochrome b and then electrons are passed on to cytochrome c resulting in oxidation of cytochrome b.

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.
