Cyanobacteria evolution
WebAbstract. Cyanobacteria have developed an effective photosynthetic CO2 concentrating mechanism (CCM) for improving the efficiency of carboxylation by a relatively inefficient Rubisco. The development of this CCM was presumably in response to the decline in atmospheric CO2 levels and rising O-2, both of which were triggered by the development … WebCyanobacteria are blue-green algae that produce chlorophyll and undergo photosynthesis. Oxygen, a byproduct of that photosynthesis, was released into the atmosphere, changing it in such a way that it may have allowed the evolution of more complex forms of life.
