CC -!- FUNCTION: Core subunit of the mitochondrial membrane respiratory chain CC NADH dehydrogenase (Complex I) that is believed to belong to the CC minimal assembly required for catalysis. Complex I functions in the CC transfer of electrons from NADH to the respiratory chain. The immediate CC electron acceptor for the enzyme is believed to be ubiquinone. CC {ECO:0000256|ARBA:ARBA00003257}. CC -!- FUNCTION: NDH shuttles electrons from NAD(P)H:plastoquinone, via FMN CC and iron-sulfur (Fe-S) centers, to quinones in the photosynthetic chain CC and possibly in a chloroplast respiratory chain. The immediate electron CC acceptor for the enzyme in this species is believed to be CC plastoquinone. Couples the redox reaction to proton translocation, and CC thus conserves the redox energy in a proton gradient. CC {ECO:0000256|HAMAP-Rule:MF_01357, ECO:0000256|RuleBase:RU003581}.
