(1) actively transport molecules in an organism

Explanation:

ATP (adenosine triphosphate) is a nucleotide made of the nitrogenous base(adenine), the sugar(ribose) and three phosphate groups which are covalently linked togther and attached to ribose.

ATP fuels cellular activities by transferring a phosphate group as seen in the attached image to a different molecule (this process is refereed to as phosphorylation).
