The first mechanism is similar to that postulated by Peter Mitchell, and is based on electrons and protons used to generate water coming from opposite sides of the membrane. After the electrons have entered the cytochrome oxidase from the cytochrome c to the Cu A molecules they will then transfer to heme a (Figure 7). Cytochrome c oxidase (CcO), a membrane enzyme in the respiratory chain, catalyzes oxygen reduction by coupling electron and proton transfer through the enzyme with a proton … oxidase in yeast.
