ATP is a compound that stores and transports energy and is the main energy source for cellular function. ATP can be produced from the breakdown of a variety of nutrients. The conversion of ATP to ADP releases phosphate. The reaction is exothermic and catabolic. The conversion of ADP to ATP is endothermic and anabolic.
