Answer 1

Sr. No.	Aerobic respiration	Anaerobic respiration
1.	It occurs in the presence of oxygen.	It occurs in the absence of oxygen.
2.	Here there is a complete breakdown of glucose releasing carbon-di-oxide, water and energy.	There is a partial breakdown of glucose into ethyl alcohol and carbon-di-oxide
3.	More energy is released (38 ATP).	Lesser energy is released (2 ATP).
4.	Aerobic respiration consists of three steps - glycolysis, krebs cycle and terminal oxidation.	Anaerobic respiration consist of two steps - glycolysis and incomplete break down of pyruvic acid.
5.	Aerobic respiration involved electron transport system.	Electron transport system is absent.
