Verified step by step guidance

Understand the role of ATP in cellular processes: ATP (adenosine triphosphate) is the primary energy carrier in cells. It provides energy for various cellular activities by undergoing hydrolysis.

Recognize the process of ATP hydrolysis: ATP hydrolysis involves the breakdown of ATP into ADP (adenosine diphosphate) and an inorganic phosphate (Pi). This reaction releases energy.

Identify the type of energy released: The energy released during ATP hydrolysis is free energy, which can be used to drive endergonic reactions in the cell.

Explore the concept of energy coupling: Cells use the free energy released from ATP hydrolysis to power other reactions that require energy, effectively coupling exergonic and endergonic processes.

Clarify why other options are incorrect: ATP does not act as a catalyst, nor does it lower activation energy directly. The release of heat is not the primary function of ATP hydrolysis in driving cellular work.
