Question
Oxygen is an essential requirement for aerobic respiration but it enters the respiratory process at the end? Discuss.

Solution
Oxygen is an essential factor for aerobic respiration because it removes hydrogen from the electron transport system. It also acts as a hydrogen acceptor. The absence of oxygen will inhibit the passage of electrons through the co-enzymes and also there won’t be a formation of proton pump and ATP will not be produced by oxidative phosphorylation.
