ATP or adenosine triphosphate is the energy molecule or energy currency of the cells (and our body). Energy is stored in the form of ATP molecules and can be easily transferred from one location to another and can also be stored for future use. ATP consists of adenine base, a ribose sugar and 3 phosphate groups. These phosphate groups are connected through high-energy bonds. ATP is formed through the process of cellular respiration, in which oxidation of food (organic matter) releases energy, which is stored as ATP. When energy is needed anywhere in the cell (for growth or division or maintenance), one of the phosphate group breaks away, releasing energy and converting ATP to ADP (Adenosine diphosphate). The ADP can be further converted to AMP (adenosine monophosphate) if additional energy is required. The cell is also capable of converting AMP or ADP to ATP if there is spare energy available for storage.

Hope this helps.
