Final answer:
ATP serves as the energy currency for cells, providing energy for cellular processes as an energy carrier in chemical reactions.
Step-by-step explanation:
ATP serves as the energy currency for cells. It stores energy briefly and transports it within the cell to support endergonic chemical reactions. The structure of ATP consists of an RNA nucleotide with three phosphate groups attached.
ATP provides energy for cellular processes by being an energy carrier in chemical reactions. As ATP is used for energy, a phosphate group is detached, and ADP is produced. It can then be recharged into ATP using energy derived from glucose catabolism.
