==Electron Source==

An electron source is needed in order for the redox reaction of O₂ to occur. Cytochrome bd oxidase uses the quinol molecule ubiquinone as an electron donor. The chemical structure of ubiquinone is shown in Fig. 2. [[Image:Ubiquinone.jpg|200 px|right|thumb|Figure 2. Chemical structure of ubiquinone.]] As shown in the <scene name='83/838655/Bdoxidase_structure_full/4'>overall structure</scene> the <scene name='83/838655/Bdoxidase_q_loop/2'>Q loop</scene> is on the extracellular surface and provides a binding site for ubiquinone. <ref name = ”Safarian” /> As mentioned in the Active Site section, Heme <scene name='83/838655/Bdoxidase_qloop_zoom/3'>B558</scene> is closest in proximity to the Q loop and thus is the suggested electron acceptor.
