The cycle of dark photosynthesis reactions is catalyzed by enzymes that occur in the chloroplasts of plants and many bacteria and involves the fixation of carbon dioxide and the formation of a 6-carbon sugar known as the Calvin cycle.
The Calvin cycle, also known as a dark reaction or a light-independent reaction, can be divided into three main stages.
Carbon fixation
Reduction
Regeneration of parent molecule
Overall, this cycle is an anabolic pathway that forms glucose from carbon dioxide and water.
However, according to the latest findings, the carbohydrate produced by the Calvin cycle is not hexose sugar (glucose with six carbon atoms).
They are triose (3 carbon) sugar phosphates, also known as triosephosphate.
It then leads to the production of hexose sugar in mitochondria.
