Detailed explanation-1: -Metabolism (pronounced: meh-TAB-uh-liz-um) is the chemical reactions in the body’s cells that change food into energy. Our bodies need this energy to do everything from moving to thinking to growing. Specific proteins in the body control the chemical reactions of metabolism.

Detailed explanation-2: -Chemical reactions that occur in biological systems are referred to as metabolism. Metabolism includes the breakdown of substances (catabolism), the formation of new products (synthesis or anabolism), or the transferring of energy from one substance to another.

Detailed explanation-3: -Catabolism is the set of metabolic processes that break down large molecules. These include breaking down and oxidizing food molecules. The purpose of the catabolic reactions is to provide the energy and components needed by anabolic reactions which build molecules.

Detailed explanation-4: -Metabolism: Converting food into energy. Metabolism is the process by which the body changes food and drink into energy. During this process, calories in food and drinks mix with oxygen to make the energy the body needs. Even at rest, a body needs energy for all it does.

Detailed explanation-5: -Catabolism. The breakdown of complex molecules into simpler ones. Exergonic reaction. A reaction that releases energy. Endergonic reaction.
