Recall the general structure of ATP (adenosine triphosphate), which is a nucleotide composed of three main parts: a nitrogenous base, a sugar, and phosphate groups.
Identify the nitrogenous base in ATP. ATP contains adenine, which is a purine base, not guanine or any other base.
Determine the sugar component. ATP contains ribose, a five-carbon sugar with a hydroxyl group on the 2' carbon, distinguishing it from deoxyribose which lacks this hydroxyl group.
Recognize the phosphate groups. ATP has three phosphate groups linked in a chain, which are critical for its role in energy transfer.
Combine these components to confirm that ATP consists of adenine, ribose, and three phosphate groups, making this the correct option.
