Lesson Summary. ATP, or adenosine triphosphate, is a high-energy molecule that is found floating in the cytoplasm of every cell. It's a three-part molecule that has a phosphate group.
Adenosine 5'-triphosphate, or ATP, is the principal molecule for storing and transferring energy in cells. It is often referred to as the energy currency of the cell and can be compared to storing money in a bank. ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell. Animals store the energy obtained from the breakdown of food as ATP.
