19+ Oxygenic And Anoxygenic Photosynthesis JPG

There are two main types of photosynthesis: Anoxygenic photosynthesis is used mainly by the purple bacteria, the green sulfur and nonsulfur bacteria, the heliobacteria and the acidobacteria.

They have revealed great similarity between the cores of the two photosynthetic systems (psi and psii) present in oxygenic organisms, and the cores of photosystems present in various groups of bacteria carrying out anoxygenic photosynthesis, indicating a common evolutionary origin of all.

For photosynthesis to continue, the electron lost from the reaction center pigment must be replaced. Similar to oxygenic photosynthesis, there is a complex process with multiple steps for anoxygenic photosynthesis, which can be summarized with the following chemical equation Anoxygenic photosynthesis has either a type i or a type ii reaction centers, but never both. Anoxygenic photosynthesis produces an electrochemical proton gradient across the membrane which habitats in which oxygenic photosynthesis is important is relatively limited in distribution and is once anoxygenic photosynthesis had evolved, the planet would have become widely habitable.
