Adenosine Triphosphate (ATP) is the primary source of energy in cells.
ATP is often referred to as the energy currency of the cell because it stores and transfers energy released from metabolic reactions to power cellular activities.
Energy is released when ATP is hydrolyzed to ADP (Adenosine Diphosphate) and inorganic phosphate. ADP can be re-phosphorylated to ATP using energy from catabolic processes like cellular respiration. AMP (Adenosine Monophosphate) and NAD (Nicotinamide adenine dinucleotide) are also important molecules in metabolism but ATP is the direct energy source for most cellular work.
