Detailed explanation-1: -Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body’s cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.

Detailed explanation-2: -Why is respiration important for digestion? Respiration provides carbon dioxide for the digestion of food. Respiration provides hydrogen for the digestion of food. Respiration provides oxygen for the combustion of food.

Detailed explanation-3: -Respiration is essential for survival of living organisms. It releases energy from the food. The oxygen we inhale is used to breakdown glucose into carbon dioxide and water. Energy is released in the process.

Detailed explanation-4: -Respiration is the process of oxidation of food to release energy. Nutrients in the cells are oxidised by the supply of oxygen which is provided to the cells by the process of respiration.

Detailed explanation-5: -Respiration is important because it produces energy that is necessary for the functioning of the body. It provides oxygen to the cells and expels toxic carbon dioxide. When oxygen reaches the cells, this oxygen breakdown glucose which is present in digested food, and releases energy.
