Cytochrome c oxidase (COX), or complex IV of the mitochondrial respiratory chain, catalyses the transfer of electrons from reduced cytochrome c to molecular oxygen, and couples this reaction to proton pumping across the inner mitochondrial membrane. The activity of the enzyme is determined colorimetrically by following the oxidation of reduced Cytochrome c as an absorbance decrease at 550 nm. �$ 21 0 obj
