Which process is ATP NOT involved in?

1

Select the equation which BEST outlines the exergonic process of ATP hydrolysis.

1

ATP hydrolysis does not change the energy of a system, but rather creates free energy for another process.

1

ATP phosphorylates molecules which would not normally react and allows endergonic processes to occur.

1

ATP hydrolysis cools the surrounding environment.

1

ATP is recyclable.
