Calvin cycle
The Calvin cycle (also known as Calvin-Benson cycle) is a series of biochemical reactions taking place in the chloroplasts of photosynthetic organisms.

Calvin cycle (aka Calvin-Benson Cycle or Carbon Fixation) Series of biochemical, enzyme-mediated reactions during which atmospheric carbon dioxide is reduced and incorporated into organic molecules, eventually some of this forms sugars.

Calvin cycle In plants, a cyclic metabolic pathway in which carbon dioxide is incorporated into ribulose 1,5-bisphosphate to give compounds that can be used for the synthesis of glucose.

Some plants have developed a preliminary step to the Calvin Cycle (which is also referred to as a C-3 pathway), this preamble step is known as C-4.

Both molecules and carbon dioxide (CO2) are needed in the light independent reaction (Calvin Cycle) to produce a hexose sugar, such as glucose, from RuBP.
Glucose is used to in the mitochondrion to produce the energy molecule ATP.

The light-independent reactions of photosynthesis (or dark reactions) of the Calvin Cycle can occur in the absence of light.

This reaction happens when the light energy is captured and pushed into a chemical called ATP. The second part of the process happens when the ATP is used to make glucose (the Calvin Cycle).

and, therefore, the evolutionary relationship of these prokaryotes to eukaryotic organelles is of interest. Chlorobium species can also fix CO2, although the biochemical pathway used by these prokaryotes is distinct from the Calvin cycle found in ...
