Dissipation of the proton gradient is coupled to the phosphorylation of ADP through membrane-bound ATPases.
Adenosine triphosphate | Guanosine diphosphate | Cyclic adenosine monophosphate | Uridine diphosphate | adenosine triphosphate | Adenosine diphosphate | Adenosine A1 receptor | Uridine diphosphate galactose |
Oxygen also occurs in phosphate (PO43−) groups in the biologically important energy-carrying molecules ATP and ADP, in the backbone and the purines (except adenine) and pyrimidines of RNA and DNA, and in bones as calcium phosphate and hydroxylapatite.
