The phosphoester bond and phosphoanhydride bonds in ATP have the approximately same free energies of hydrolysis.

Question

Quizplus · Accepted Answer

Phosphoanhydride bonds (found between the phosphate groups in ATP) have a higher free energy of hydrolysis compared to the phosphoester bonds (such as those linking a phosphate group to an organic molecule). This difference in energy is what makes the hydrolysis of ATP to ADP and inorganic phosphate a highly exergonic reaction, providing energy for cellular processes.
