Which of the following is the correct sequence of the electron transport chain?
Correct answer: A. Cytochrome b, c, a, a3
- A. Cytochrome b, c, a, a3
- B. Cytochrome c, b, a3, a
- C. Cytochrome a3, b, c, a
- D. Cytochrome a, a3, b, c
Explanation
The electron transport chain involves the transfer of electrons through a specific sequence of cytochromes: b, c, a, and a . This sequence is essential for proper electron flow and ATP synthesis.

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.
