ATP is formed when energy is released during photosynthesis.b. When ADP + P becomes ATP, the amount of energy released is enough
puteri [66]

Answer:

c. ATP is comprised of a sugar, base, and three phosphate groups

Explanation:

ATP is the energy currency of cells and is formed during the phosphorylation of ADP. The process of ATP formation is endergonic and is often coupled with some exergonic process.

One molecule of ATP consists of one ribose sugar, an adenine base (a purine base) and three phosphate groups. Breakage of phosphoanhydride bond during hydrolysis of ATP into ADP and inorganic phosphate release a large amount of energy.
