What is the name of the high-energy compound that cells use oth directly to fuel other chemical reactions?
ATP, or adenine tri-phosphate, or adenosine triphosphate, consists of an adenine molecule, as well as three inorganic phosphates. The three inorganic phosphates don't like to be attached to the adenine, so it's common for the third (and sometimes the second, in ADP - adenosine diphosphate) inorganic phosphate group to detach. When doing so, the bond - which stores a great deal of potential energy - is dissociated, converting the potential energy into kinetic energy. This energy is used to fuel endergonic chemical reactions.
