Cytochrome c Oxidase: A Brief Introduction and Some New Results from High Field Endor Studies of The CuA and CuB Sites

A Mitchellian view of mitochondrial respiration is presented in Scheme I.1,2 This illustrates electron transfer from an electron rich material, NH, through quinone, Q, through Complex HI, into cytochrome c, and through Complex IV(cytochrome c oxidase) to O2, with accompanying proton translocations across the lipid bilayer.
