You are given a beaker containing a solution of an enzyme that hydrolyzes adenosine triphosphate (ATP) while it generates a lot of heat. You add a substantial amount of the sodium salt of ATP, and you measure the temperature of the beaker, and determine that nothing is happening. The enzyme is not performing the reaction. What is a reasonable chemical to add to the solution to get the enzyme to proceed with the hydrolysis of adenosine triphosphate
