Photophosphorylation differs from oxidative phosphorylation in requiring the input of energy in the form of light to create a good electron donor and a good electron acceptor. In photophosphorylation, electrons flow through a series of membrane-bound carriers including cytochromes, quinones, and iron-sulfur proteins, while protons are pumped across a membrane to create an electrochemical potential. Electron transfer and proton pumping are catalyzed by membrane complexes homologous in structur...
