Question

Explain the process of Cellular Respiration.

Answer 1

Cellular Respiration is a biochemical process which involves the oxidation of glucose to release energy, carbon dioxide, and water are released as by-products.

\[\ce{\underset{\text{glucose}}{C6H12}\underset{\text{oxygen}}{O6+6O2}->[enzymes]\underset{\text{Carbon dioxide}}{6CO2}+ \underset{\text{water}}{6H2O}+energy}\]

It involves a series of chemical reactions controlled by different enzymes. The energy released in the process is stored in the form of an energy-rich substance called ATP (Adenosine triphosphate). The ATP molecules are stored in the cells and later on can be broken down to release energy for various metabolic activities. The entire process takes place partially in the cytoplasm and partially in the mitochondria of our body cells. The process of conversion of glucose molecules in food into energy-rich molecules, CO2 and water with the help of oxygen is known as respiration
