What Is Metabolism?

Metabolism is the chemical reaction 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. Thousands of metabolic reactions happen at the same time

Anabolism:

Anabolism or constructive metabolism is all about building and storing. It supports the growth of new cells, the maintenance of body tissues, and the storage of energy for future use. In anabolism, small molecules change into larger, more complex molecules of carbohydrates, protein, and fat.

Catabolism:

Catabolism or destructive metabolism is the process that produces the energy needed for all activity in the cells. Cells break down large molecules (mostly carbs and fats) to release energy. This provides fuel for anabolism, heats the body, and enables the muscles to contract and the body to move.

As complex chemical units break down into more simple substances, the body releases the waste products through the skin, kidneys, lungs, and intestines.
