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.
