The role of oxygen in respiration is:
Correct answer: D. It is the final electron acceptor at the end of the electron transport chain
- A. It combines with acetyl-CoA at the start of the Krebs cycle
- B. It plays no role
- C. It is given off as a by-product during the oxidation of pyruvates
- D. It is the final electron acceptor at the end of the electron transport chain
Explanation
"The explanation for this question will be added soon!"In the electron transport chain , oxygen acts as the final electron acceptor and accepts electron and then reacts with 2H+ ions and forms water.

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.
