1) Three stages of cellular respiration is Glycolysis, TCA cycle and electron transport chain.
2) In aerobic respiration, oxygen is final electron acceptor
3) Sulfur, nitrate or sulphate are final electron acceptor in anaerobic respiration.
4) Organisms capable of aerobic respiration reduce oxygen to water.
