RUBRUM 301 HYPOTHETICAL SCHEME ON PHOSPHORYLATING, PHOTOSYNTHETIC ELECTRON TRANSPORT SYSTEM In summary, a hypothetical scheme for the electron transport sys- tem in "intact" chromatophores of R. rubrum is presented (Fig, 21). Under anaerobic conditions, electrons migrate through the electron transport system in a cyclic fashion at the expense of the energy absorbed from light in bacteriochlorophyll (BChl) and its accessory pigment, carotenoids. The oxidation-reduction reactions around both flavoprotein (FP) and cytochrome c 9 are able to couple phosphorylating reactions.
