Question

what is complex 4 in electron transport system of mitrocondria. mention its components
​

Answer 1

Explanation:

Cytochrome oxidase (complex IV) catalyzes this transfer of electrons. Cytochromes a and a3 each contain a heme and two different proteins that each contain copper. Two electrons are required to reduce one atom of oxygen; therefore, for each NADH that is oxidized, one-half of O2 is converted to H2O.
