The three hemes are located near the periplasmic space, meaning that the membrane potential is generated mainly from proton transfer from the cytoplasm towards the active site on the opposite site of the membrane. Heme''b558'' is involved in quinol oxidation and Heme''d'' serves as the site where O2 binds and becomes reduced to H2O.]] | [[Image:proton graadient.jpg|300 px|left|thumb|Figure 1: Overall schematic representation of cytochrome bd. <ref name= "Giuffre">PMID: 24486503</ref>; General display of the reduction of molecular oxygen into water using the quinol as a reducing substrate.
