What energy-storing molecule is composed of adenine molecules?

• A. Adenosine Triphosphate (ATP)
• B. Adenosine Diphosphate (ADP)
• C. Guanosine Triphosphate (GTP)
• D. Deoxyadenosine Triphosphate (dATP)

Answer: (A)

Adenosine Triphosphate (ATP) is the primary energy-storing molecule in cells and is composed of an adenine base, ribose sugar, and three phosphate groups. The presence of the adenine molecules is crucial because they serve as the nitrogenous base that forms a vital part of the structure. When ATP is hydrolyzed to release energy, one of its phosphate groups is removed, resulting in the formation of ADP (Adenosine Diphosphate) and an inorganic phosphate. However, in the context of the question, ATP is specifically identified as the molecule that is made up of adenine. Other options like ADP, GTP, and dATP, while associated with energy transfer, either consist of fewer phosphate groups or involve different nitrogenous bases, thus not fitting the criteria of being composed of adenine molecules directly.
