Lesson Summary. ATP, or adenosine triphosphate, is a high-energy molecule that is found floating in the cytoplasm of every cell. It's a three-part molecule that has a phosphate group.
Adenosine triphosphate (ATP) (shown in Figure 1) is the main molecule used for energy transfers and transport within cells. It is also one of the monomers used in the synthesis of RNA and, after it is converted to deoxyATP (dATP), in the synthesis of DNA.
