Abstract:
We have found the ATP production in the Rhodobacter sphaeroides chromatophores illuminated by single short light flash, that is under conditions when the proton gradient formed as a result of electron transport after the second flash, is absent. The ATP synthesis was accompanied by the H2O2 formation. Simultaneous formation of H2O2 is indicative of the oxidative activation of phosphate during the ATP synthesis, as in the model systems with isolated chlorophyll. These data provide a theoretical background to the fitting of illumination parameters in both laboratory and industrial photobioreactors with photosynthetic bacteria used in biotechnological processes.

Photosystem I
Both these photosystems work in concert. An excited electron from PSII is relayed to PSI via an electron transport chain in the thylakoid membrane of the chloroplast, which is comprised of the carrier molecule plastoquinone, the dual-protein cytochrome complex, and plastocyanin. As electrons move between PSII and PSI, they lose energy and must be re-energized...
