Adenosine Triphosphate, more commonly referred to as ATP, is the basic energy unit of the cell.
ATP is comprised of an adenine base and ribose (Adenosine) and three phosphate groups (Triphosphate). The adenosine is generally depicted to the left of the phosphate groups. There is a very strong bond between the second and third phosphates. This is the bond that provides the energy for the cell. When this bond is broken, much energy is released. This powers much of the cell's activities.
ATP is the basic energy unit of the body. Cells use the energy from ATP for movement and endergonic reactions.
ATP is formed by one phosphate group attaching to ADP.
