18. PHOTOTROPHIC BACTERIA AND PHOTOSYNTHESIS

18.3. PHOTOSYNTHESIS PROCESSES

Photosynthesis is The conversion of light energy into biochemically accessible energy (ATP) and reducing equivalents [NAD(P)H], coupled with the synthesis of cellular components.

The equation for photosynthesis in green plants is as follows

The equation for photosynthesis in phototrophic Bacteria is as follows

The general equation for photosynthesis can be represented as

The basis of any photosynthesis is the same primary process, whereas Different types of photosynthesis differ from one another only in The Nature of the hydrogen donor (Water, hydrogen sulfide, Organic compounds). For water to serve as a hydrogen donor, two consecutive photoreactions are required. When utilizing Donors with a more negative redox potential (such as hydrogen sulfide), a single photoreaction is sufficient.
