Understand that ATP stands for Adenosine Triphosphate, which is a molecule used by cells for energy transfer.
Recognize that ATP is composed of three main components: a nitrogenous base, a sugar, and phosphate groups.
Identify the nitrogenous base in ATP as adenine, which is a purine base.
Note that the sugar in ATP is ribose, a five-carbon sugar, which differentiates it from DNA, where the sugar is deoxyribose.
Acknowledge that ATP contains three phosphate groups, which are key to its role in energy transfer, as the bonds between these phosphates store potential energy.
