Verified step by step guidance

Understand the role of ATP (adenosine triphosphate) in cellular processes. ATP is the primary energy carrier in cells, providing energy for various biochemical reactions.

Recognize that ATP participates in energy-coupling reactions by transferring a phosphate group to other molecules. This process is known as phosphorylation.

Phosphorylation involves the transfer of a phosphate group from ATP to a target molecule, which often results in a change in the target molecule's structure and function, thereby activating or deactivating it.

This transfer of a phosphate group releases energy stored in the high-energy bonds of ATP, which can then be used to drive endergonic (energy-requiring) reactions in the cell.

Understand that ATP does not directly convert light energy into chemical energy, act as a structural component of cell membranes, or store energy in the form of glucose. Its primary role is to transfer energy through phosphorylation.
