Detailed explanation-1: -Answer and Explanation: Enzymes directly controls the rate at which food is broken down to release energy. Enzymes significantly regulate the rate of chemical reactions going in the body. They are important for the body and take part in several reactions such as help in digestion and metabolism.

Detailed explanation-2: -The process of breakdown of food in the cell with the release of energy is called cellular respiration. Cellular respiration takes place in the cells of all organisms. In the cell, the food (glucose) is broken down into carbon dioxide and water using oxygen.

Detailed explanation-3: -Glucose and other food molecules are broken down by controlled stepwise oxidation to provide chemical energy in the form of ATP and NADH.

Detailed explanation-4: -Chemical energy is the energy derived from the digestion of food. Chemical energy is stored in the bonds of molecules and compounds. When animals eat food, the digestion process breaks down the food into nutrients, which contain chemical energy.

Detailed explanation-5: -Cellular respiration is the process by which the energy in food is converted into energy that can be used by the body’s cells. The energy stored in glucose is transferred to ATP. The process can be summarized as: glucose + oxygen carbon dioxide + water.
