ATP hydrolysis, ATP + H2O → ADP + Pi, is the exothermic chemical reaction that provides the energy for many of the processes that take place in a cell. The reaction is described as arising from "breaking a phosphate bond in ATP" that is often described as a "high energy bond." The reaction also forms an OH-P bond to create Pi. Just consider this reaction in isolation. Which of the following statements would you therefore expect are true about the reaction? It only takes a little energy to break the O-P bond in ATP. The OH-P bond that is formed in the reaction is a weak bond. The OH-P bond that is formed in the reaction is a strong bond. It takes a lot of energy to break the O-P bond in ATP. The formation of the OH-P bond is the part of the reaction responsible for releasing energy. The breaking of the O-P bond releases energy that is stored in the bond.
