  • 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:0045271 Respiratory chain complex I is an enzyme of the respiratory chain. It consists of several polypeptide chains and is L-shaped, with a horizontal arm lying in the membrane and a vertical arm that projects into the matrix. The electrons of NADH enter the chain at this complex.
  • GO:0008137 Catalysis of the reaction: NADH + ubiquinone + 5 H+(in) = NAD+ + ubiquinol + 4 H+(out).
  • GO:0048039 Binding to ubiquinone, a quinone derivative with a tail of isoprene units.
  • GO:0009060 The enzymatic release of energy from inorganic and organic compounds (especially carbohydrates and fats) which requires oxygen as the terminal electron acceptor.
  • 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:0015990 The transport of protons against an electrochemical gradient, using energy from electron transport.
