Bacteriochlorophyll (Bchl) is distributed in two fractions, quite distinct functionally. A small fraction, about 3% of the total, forms part of the photoreaction center (RC), which carries out the photochemical reaction. The rest of the Bchl belongs to the light harvesting (LH) antenna, which absorbs radiant energy and transfers it to the RC. In an...

11. Such near infrared changes are very similar to those observed upon light-induced or dark oxidation of photoreaction center bact- eriochlorophyll (the primary donor of bacterial photosynthesis), i.e., a bleaching at 865 nm and increase in optical density at 1245 nm [2]. Besides, the oxidized primary donor exhibits an ESR signal with a Gaussian l...

The photosynthetic pigments are associated with specific apoproteins to form several types of complexes.
