Early in the morning of June 17, 1972, several burglars were arrested inside the office of the Democratic National Committee (DNC), located in the Watergate building in Washington, D.C.
A critically important macromoleculeâarguably âsecond in importance only to DNAââis ATP. ATP is a complex nanomachine that serves as the primary energy currency of the cell (Trefil, 1992, p.93). A nanomachine is a complex precision microscopic-sized machine that fits the standard definition of a machine. ATP is the âmost widely distributed high-energy compound within the human bodyâ (Ritter, 1996, p. 301).
KEY ENERGY PROCESSES IN CELLS. Most of what a cell does involves endergonic reactions, requiring constant energy input; these reactions are coupled to just a few exergonic reactions which supply that energy. The key fuel source in cell reactions is Adenosine Triphosphate, or ATP.EY ENERGY PROCESSES IN CELLS.
