  • GO:0042773 The transfer of electrons through a series of electron donors and acceptors, generating energy that is ultimately used for synthesis of ATP.
  • GO:0008137 Catalysis of the reaction: NADH + ubiquinone + 5 H+(in) = NAD+ + ubiquinol + 4 H+(out).
  • GO:0012505 A collection of membranous structures involved in transport within the cell. The main components of the endomembrane system are endoplasmic reticulum, Golgi bodies, vesicles, cell membrane and nuclear envelope. Members of the endomembrane system pass materials through each other or though the use of vesicles.
  • 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:0050136 Catalysis of the reaction: NADH + H+ + a quinone = NAD+ + a quinol.
  • GO:0048038 Binding to a quinone, any member of a class of diketones derivable from aromatic compounds by conversion of two CH groups into CO groups with any necessary rearrangement of double bonds.
