Question

List in tabular form the two differences between aerobic and anaerobic respiration. Why do we feel cramps in our muscles during sudden physical activity ?

Answer 1

Difference between Aerobic and Anaerobic respiration :

S No.	Aerobic Respiration	Anaerobic Respiration
(i)	Occurs in the presence of oxygen.	Occurs in the absence of oxygen.
(ii)	Releases a large amount of energy.	Releases a relatively small amount of energy.

During sudden physical activity, there is a lack of oxygen in our muscles cells, the pathway for the breakdown of pyruvate into lactic acid that develops cramps in the body.
