CC   -!- FUNCTION: Transfer of electrons from NADH to the respiratory chain. The
CC       immediate electron acceptor for the enzyme is believed to be
CC       ubiquinone.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a ubiquinone + 5 H(+)(in) + NADH = a ubiquinol + 4 H(+)(out) +
CC         NAD(+); Xref=Rhea:RHEA:29091, Rhea:RHEA-COMP:9565, Rhea:RHEA-
CC         COMP:9566, ChEBI:CHEBI:15378, ChEBI:CHEBI:16389, ChEBI:CHEBI:17976,
CC         ChEBI:CHEBI:57540, ChEBI:CHEBI:57945; EC=7.1.1.2;
CC   -!- SUBUNIT: Complex I is composed of about 40 different subunits.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane; Single-pass
CC       membrane protein.
