  • GO:0009319 A protein complex that possesses cytochrome o ubiquinol oxidase activity; consists of four polypeptide subunits and associated prosthetic groups.
  • GO:0005886 The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
  • GO:0009486 Catalysis of the reaction: 2 ubiquinol + O2 + 4 H+ = 2 ubiquinone + 2 H2O + 4 H+ [periplasmic space].
  • GO:0004129 Catalysis of the reaction: 4 Fe(II)-[cytochrome c] + O2 + 8 H+(in) = 4 Fe(III)-[cytochrome c] + 2 H2O + 4 H+(out).
  • GO:0019646 A process in which a series of electron carriers operate together to transfer electrons from donors such as NADH and FADH2 to oxygen to generate a transmembrane electrochemical gradient.
  • GO:0015990 The transport of protons against an electrochemical gradient, using energy from electron transport.
  • GO:0022904 A process in which a series of electron carriers operate together to transfer electrons from donors such as NADH and FADH2 to any of several different terminal electron acceptors to generate a transmembrane electrochemical gradient.
  • GO:0009055 A molecular function representing the directed movement of electrons from one molecular entity to another, typically mediated by electron carriers or acceptors, resulting in the transfer of energy and/or the reduction-oxidation (redox) transformation of chemical species. This activity is fundamental to various biological processes, including cellular respiration and photosynthesis, as well as numerous enzymatic reactions involved in metabolic pathways.
  • GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it.
