Which of the following is NOT a function of ATP in cells?

ATP, or adenosine triphosphate, plays a crucial role in cellular processes, primarily as an energy carrier. Its main functions include transferring energy to various biochemical reactions, supporting metabolic pathways, and facilitating numerous cellular functions by providing the energy necessary for those processes to occur.

In contrast, storing genetic information is not a function of ATP. Genetic information is primarily stored in DNA molecules, which have a distinct structure and role separate from that of ATP. DNA encodes the instructions needed for the development, functioning, and reproduction of all living organisms, whereas ATP is directly involved in energy transfer rather than information storage. This distinction underscores why the process of storing genetic material does not involve ATP, making it the correct choice for this question.
