Sl.
No.
Aerobic RespirationAnaerobic Respiration
1.It utilizes oxygen.It does not utilize oxygen.
2.Food molecules (glucose) completely break down.Food molecules (glucose) partially break down.
3.Carbon dioxide and water are formed.Ethanol along with carbon dioxide (in plants) and lactic acid (in animals) are formed.
4.More energy is released (38 ATP molecules).Less energy is released (2 ATP molecules).

Chemical equations of the two kinds of respiration in plants are:

(i) Aerobic:

Glucose + Oxygen Enzymes\xrightarrow{\text{Enzymes}} Carbon dioxide + water + Energy (38 ATP)

(ii) Anaerobic:

Glucose Enzymes\xrightarrow{\text{Enzymes}} Ethanol + Carbon dioxide + Energy (2 ATP)
