ATP (adenosine triphosphate) contributes to cellular processes, especially endothermic reactions, as an immediate and versatile energy currency. During cellular activities requiring energy, ATP undergoes hydrolysis, breaking its high-energy phosphate bonds and releasing energy. This released energy is utilized to drive endothermic reactions that require an input of energy. ATP’s structure with three phosphate groups allows it to store and release energy easily. The conversion of ATP to ADP (adenosine diphosphate) during these reactions is reversible, ensuring a continuous energy supply. This dynamic interconversion of ATP and ADP plays a pivotal role in powering various energy-demanding cellular processes.
