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: -By definition, an organism’s metabolism describes all of the different chemical reactions that take place within the organism. These reactions can be anabolic, building up complex molecules from simple ones. They can also be catabolic, breaking down complex molecules to release energy.

Detailed explanation-3: -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-4: -Classification. Cellular metabolism has two distinct divisions: anabolism and catabolism. Anabolism is a constructive metabolic process in which a cell uses energy to construct molecules such as enzymes and nucleic acids and perform other essential life functions.

Detailed explanation-5: -metabolism, the sum of the chemical reactions that take place within each cell of a living organism and that provide energy for vital processes and for synthesizing new organic material.
