Answer;

-ATP; Nuceotide.

ATP is the main source of chemical energy that drives all cellular work and belongs to the class of organic molecules known as Nucleotide.

Explanation;

-ATP, adenosine triphosphate, is a high energy molecule, powers (drives) nearly all forms of cellular work. Hydrolysis of ATP releases energy by transferring its third phosphate from ATP to some other molecule in a process called phosphorylation.

-ATP is a nucleic acid. Specifically it is a nucleotide. ATP is one of four nucleic acid bases that forms the polymer RNA. In metabolism, ATP is a form of stored chemical energy.

-ATP consists of the adenine nucleotide (ribose sugar, adenine base, and phosphate group, PO4-2) plus two other phosphate groups. Energy is stored in the covalent bonds between phosphates, with the greatest amount of energy in the bond between the second and third phosphate groups.

i think it would be b. tissue because an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.
