Detailed explanation-1: -Anaerobic respiration produces a relatively lesser amount of energy as compared to aerobic respiration, as glucose is not completely broken down in the absence of oxygen.

Detailed explanation-2: -Aerobic respiration takes place in presence of oxygen; whereas anaerobic respiration takes place in absence of oxygen. Carbon dioxide and water are the end products of aerobic respiration, while alcohol is the end product of anaerobic respiration. Aerobic respiration releases more energy than anaerobic respiration.

Detailed explanation-3: -However, in anaerobic respiration, the breakdown of glucose is incomplete. The end product of anaerobic respiration is lactic acid instead of carbon dioxide and water. This process occurs in oxygen debt. Hence, the amount of oxygen required to oxidize lactic acid to carbon dioxide and water is not present.

Detailed explanation-4: -Aerobic respiration includes the exchange of gases between the organism and the outside environment. In anaerobic respiration exchange of gases is absent. Anaerobic respiration occurs in lower organisms such as lactic acid bacteria, E. Coli, staphylococcus, clostridium, yeast, etc.

Detailed explanation-5: -The breakdown of glucose occurs in the cells of an organism (cellular respiration). If the food is broken down with the use of oxygen, it is called aerobic respiration. If the breakdown occurs without the use of oxygen, the respiration is called anaerobic respiration.
