The taxon that consists of one or more genera (plural form of genus) is the <u>family</u>.
Explanation:
According to the modern taxonomic classification system, there are eight major levels of division – Domain, Kingdom, Phyllum, Class, Order, Family, Genus, and Species.
Family is the taxonomic order which comes next to the Order and before Genus and consists of one or more genus or genera but sharing a common attributes. The ancestral origin of the family members remains the same.
The kinds of families depend upon the Kingdoms and Orders in the taxonomy. Carl Linnaeus termed family as familia in his classification and divided the major plant groups or families as trees, palms, ferns etc.
Among the family of carnivores in animals, there are many genera like Canidae, Felidae Ursidae etc.
The protein complexes in the cristae that contribute to the H+ gradient (electromotive force) across the cristae membrane include; complexes I (NADH/ubiquinone oxidoreductase), II (succinate dehydrogenase), III (cytochrome c reductase) and IV (cytochrome c oxidase).
Complex I feeds an electron from NADH to a quinol molecule ( concomitantly pumping four protons from the matrix into the crista lumen). Complex III transfers the electron from quinol to cytochrome C (concomitantly pumping one proton). Complex IV transfers the electron from cytochrome c to an oxygen molecule (concomitantly forming a water molecule and pumps four protons).
This H+ gradient is then harnessed by ATP synthase to form ATP by phosphorylating ADP.
NADH+H+ → Complex I → Q → Complex III → cytochrome c → Complex IV → H2O
