ATP as Energy Currency

ATP, or adenosine triphosphate, is often referred to as the energy currency of the cell because it stores and transports chemical energy within cells, enabling various biological processes such as metabolism, muscle contraction, and active transport. Its high-energy phosphate bonds release energy when hydrolyzed, making ATP a crucial molecule for sustaining cellular functions.
