Which one of the following is the end product in electron transport chain taking place at inner mitochondrial membrane?
Correct answer: D. Water
- A. Carbon dioxide
- B. NADPH
- C. Oxygen
- D. Water
Explanation
The end product of the electron transport chain (ETC) in the inner mitochondrial membrane is water (H₂O). In the final step, oxygen acts as the terminal electron acceptor, combining with electrons and protons to form water. This process also contributes to the generation of ATP through oxidative phosphorylation.
