When ATP is hydrolyzed to ADP and inorganic phosphate, a large quantity of energy is released. This energy is contained in the bonds between the three phosphate groups in ATP. Why are the phosphate bonds in ATP high-energy bonds? O because of very high potential for hydrogen bonding with water O because the phosphate groups have high affinity for H* ions O because there is a reactive oxygen atom between the phosphates O because the phosphates have very strong attractions for each other O because there are so many negative charges close together
