Adding a 5-carbon compound. In plants, the carbon dioxide is obtained in the sheet with the help of spores known as stomata and scattered in the stroma of the chloroplast, the location of the reactions of the Calvin cycle. These reactions are also known as light-independent reactions, since they are not directly mediated by the light. In the Calvin cycle, carbon atoms from carbon dioxide are fixed and are used to generate three-carbon sugars. One of the stages of the Calvin cycle is carbon fixation. In the fixation of carbon, one molecule of carbon dioxide combines with a five carbon acceptor molecule, RuBP (ribulose-1,5-bisphosphate), catalyzed by the enzyme rubisco.
