How is ATP utilized to drive endothermic reactions in the cell?

ATP drives endothermic reactions in the cell by releasing energy stored in its high-energy phosphate bonds. In endothermic reactions, where energy is absorbed, ATP hydrolysis occurs, breaking one of ATP’s phosphate bonds to form adenosine diphosphate (ADP) and inorganic phosphate (Pi). This reaction releases energy that is utilized to fuel energy-consuming processes. The released energy provides the necessary activation energy for endothermic reactions to proceed, facilitating cellular functions like active transport, biosynthesis, and muscle contraction. The cycling between ATP and ADP ensures a continuous supply of energy for endothermic reactions essential for cellular activities.
