Cytochromes are electron transport intermediates containing?
Correct answer: B. Haem
- A. Myoglobin
- B. Haem
- C. Globulin
- D. Fibrin
Explanation
Cytochromes are proteins that contain "haem" as a prosthetic group. They function as electron carriers in redox reactions, playing a vital role in cellular respiration and energy production, ATP.

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.
