Detailed explanation-1: -In plants, carbon dioxide (CO2) enters the chloroplast through the stomata and diffuses into the stroma of the chloroplast-the site of the Calvin cycle reactions where sugar is synthesized. The reactions are named after the scientist who discovered them, and reference the fact that the reactions function as a cycle.
Detailed explanation-2: -The primary function of the Calvin cycle is carbon fixation, which is making simple sugars from carbon dioxide and water.
Detailed explanation-3: -In the Calvin cycle, carbon dioxide is fixed to an organic substrate and then sugars are formed. This is a biosynthetic cycle.
Detailed explanation-4: -The primary product of the Calvin cycle is glyceraldehyde three phosphate or G3P. G3P is then used to synthesize glucose, and glucose is then used as the monomeric monosaccharide to produce larger polymeric polysaccharides. The Calvin cycle is also called the dark reactions of photosynthesis.
