Question

Write short note on aerobic respiration and anaerobic respiration.

Answer 1

Aerobic respiration:
i. The respiration, which takes place in the presence of oxygen, is known as aerobic respiration.
ii. During this process, food (Glucose) is broken down into carbon dioxide and water in the presence of oxygen.
iii. Energy released in this process is stored in the form of ATP (Adenosine Triphosphate).
Anaerobic respiration:
i. The respiration, which takes place in the absence of oxygen, is known as anaerobic respiration.
ii. It is commonly seen in microorganisms like bacteria, fungi, some parasites and muscle cells.
iii. In anaerobic respiration, in microorganisms, glucose is broken down into ethanol and carbon dioxide with the release of energy. In a muscle cell, lactic acid is the end product of respiration while in plants $C{O}_2$ and ethanol are formed.
