ATP consists of adenosine (composed of an adenine ring and a ribose sugar) and three phosphate groups (triphosphate). ATP releases energy by bonding with water (a process called hydrolysis.) This causes one of the phosphate molecules to be released, resulting in the formation of a new compound called adenosine diphosphate (ADP.) The release of the phosphate molecule through hydrolysis liberates approximately 12,000 calories of energy.
This question asks for a description on ATP and the role it plays in plants. ATP is a central molecule in animals, but it also plays a role in plants. The solution describes, in 267 words, the structure of ATP and the function of it in photosynthesis reactions in the plant.
