Cytochrome c and cytochrome c oxidase
WebCytochrome c oxidase (COX) is the terminal enzyme of the mitochondrial respiratory chain. It is a multi-subunit enzyme complex that couples the transfer of electrons from cytochrome c to molecular oxygen and contributes to a proton electrochemical gradient across the inner mitochondrial membrane. WebCytochrome c oxidase [EC 1.9.3.1] is located on the inner mitochondrial membrane dividing the mitochondrial matrix from the intermembrane space, and has traditionally been used as a marker for this membrane. It is also located in the cytoplasmic membrane of bacteria. Cytochrome c oxidase provides energy for the cell by coupling electron ...
