Cellular respiration is an energy releasing enzymatically controlled catabolic process which involves a step-wise oxidative breakdown of organic substances inside living cells. It may be aerobic or anaerobic in nature depending on the use of oxygen. Aerobic respiration consists of three steps glycolysis, Krebs’s cycle and terminal oxidation. Anaerobic respiration does not use oxygen as an oxidant. The two common products are ethyl alcohol and lactic acid.
Cellular respiration having many types such as : Aerobic Respiration, Anaerobic Respiration, Catabolic Reaction ( Redox reaction and fermentation ).
