Detailed explanation-1: -Cells are constantly carrying out thousands of chemical reactions needed to keep the cell, and your body as a whole, alive and healthy. These chemical reactions are often linked together in chains, or pathways. All of the chemical reactions that take place inside of a cell are collectively called the cell’s metabolism.

Detailed explanation-2: -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-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: -A cell’s metabolism refers to the combination of chemical reactions that take place within it. Catabolic reactions break down complex chemicals into simpler ones and are associated with energy release. Anabolic processes build complex molecules out of simpler ones and require energy.

Detailed explanation-5: -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.
