CC pathways, to NADH, which can enter the respiratory chain for energy
CC generation. {ECO:0000256|ARBA:ARBA00002842}.
CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692;
CC Evidence={ECO:0000256|PIRSR:PIRSR000350-3};
CC Note=Binds 1 FAD per subunit. {ECO:0000256|PIRSR:PIRSR000350-3};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|ARBA:ARBA00004496}.
