About the Model of Bacterial Photosynthesis

Description: At the base of photosynthesis of green sulfur bacteria lies an oxidation-reduction reaction of transferring hydrogen from hydrogen sulfide to carbon dioxide, accomplished with the participation of light energy. Based on experiments the author concludes that chlorophyll in the process of photosynthesis plays the role of optical sensitizer.
