What type of organic compound is used to store and release large amounts of energy?

A carbohydrate is an organic compound such as sugar or starch, and is used to store energy. Like most organic compounds, carbohydrates are built of small, repeating units that form bonds with each other to make a larger molecule. In the case of carbohydrates, the small repeating units are called monosaccharides.

Adenosine triphosphate (ATP) is also an organic compound that storages (provides) energy to drive many processes in living cells.
