Final answer:
The statement that ATP is a nucleotide is true. ATP consists of adenine, ribose sugar, and three phosphate groups, serving as the cell's primary energy currency.
Step-by-step explanation:
True or False: ATP is a nucleotide. This statement is true. Adenosine Triphosphate (ATP) is indeed a nucleotide, which is a fundamental component of cellular energy transfer. ATP is composed of three main parts: a nitrogenous base (adenine), a five-carbon sugar (ribose), and three phosphate groups. The structure of ATP is more complex than that of glucose, and it serves as the primary energy currency of the cell.
ATP carries energy within its bonds, particularly between the phosphate groups. When ATP is converted to ADP (adenosine diphosphate) by releasing a phosphate group, energy is released and used for various cellular activities. These activities include muscle contractions, transportation of substances across cell membranes, and driving anabolic chemical reactions which are essential for sustaining life.
