MeSH definition : A multisubunit enzyme complex containing CYTOCHROME A GROUP; CYTOCHROME A3; two copper
atoms; and 13 different protein subunits. It is the terminal oxidase complex of the
RESPIRATORY CHAIN and collects electrons that are transferred from the reduced CYTOCHROME
C GROUP and donates them to molecular OXYGEN, which is then reduced to water. The
redox reaction is simultaneously coupled to the transport of PROTONS across the inner
mitochondrial membrane.;
