Using ATP to Provide Energy for Biological Processes The hydrolysis of ATP provides the energy for many biological processes. For
example, these coupled reactions summarize how hydrolysis of ATP provides
the energy for a muscle protein to change shape and contract the muscle a tiny
bit. Many repeats of this process result in muscle contraction.

8. Explain why the top reaction is called the hydrolysis of ATP. (Hint: Hydro means
water and lysis means breaking down or separating.)
