ATP: Adenosine Triphosphate

Free Response

Do you think that the EA for ATP hydrolysis is relatively low or high? Explain your reasoning.


The activation energy for hydrolysis is very low. Not only is ATP hydrolysis an exergonic process with a large −∆G, but ATP is also a very unstable molecule that rapidly breaks down into ADP + Pi if not utilized quickly. This suggests a very low EA since it hydrolyzes so quickly.
