Cytochrome electron transport

WebFigure 1: The bacterial electron transport chain is a series of protein complexes, electron carriers, and ion pumps that are used to pump H + out of the bacterial cytoplasm into the extracellular space. The last enzyme in the electron transport chain can be (depends on the species) cytochrome c oxidase. WebThe electron traveling to the Reiske Center is transferred to cytochrome c 1 and then onto the attached cytochrome c, which is then released to migrate to Complex IV. The second electron travels to cytochrome b where it is used to partially reduce a coenzyme Q (ubiquinone) to the form ubisemiquinone.
