This molecule functions as the substrate to adenylate cyclase enzymes, and this molecule is made up of a purine base attached to a pentose sugar. This molecule notably contains two high energy bonds, and glycolysis yields two of these molecules. Most active transporters derive their energy from these molecules. The bulk of the production of this molecule occurs when protons pass through its namesake "synthase" enzyme after the electron transport chain. For 10 points, name this molecule often called the "molecular currency of the cell."
