In this article we will discuss about the process of oxygenic and anoxygenic photosynthesis in bacteria. Oxygenic Photosynthesis in Bacteria: Light Reaction in Cyanobacteria: In cyanobacteria (also in all phototrophic eukaryotes), there are two distinct but interconnected photosystems: photosystem I and photosystem II (Fig. 25.4). Photosystem I absorbs longer wavelength light (far-red light) and funnels […]
