Prokaryotic cyanobacteria

During prebiotic times, water-soluble ferrous iron was present and was used in the first stage of life, while copper was in the water-insoluble Cu(I) state, as highly insoluble sulphides. About 109 years ago the metabolism of a primitive prokaryote (cyanobacteria) led to the evolution of dioxygen into the Earth s atmosphere. A...

All oxygenic (oxygen-evolving) organisms from the simplest prokaryotic cyanobacteria to the most complicated land plants have a common pathway for the reduction of CO2 to sugar phosphates. This pathway is known as the reductive pentose phosphate (RPP), Calvin-Benson or C3 cycle.
