In electron transport chain, the electrons from NADH and FADH2 are passed to:
Correct answer: D. Coenzyme Q
- A. Cytochrome a
- B. Cytochrome a3
- C. Coenzyme C
- D. Coenzyme Q
Explanation
This option is the correct answer. Coenzyme Q (also known as ubiquinone) is involved in the electron transport chain, but it acts as a carrier rather than directly accepting electrons from NADH and FADH2. Coenzyme Q transfers electrons between complex I or II and complex III in the electron transport chain.
