WebCalvin cycle occurs in all the plants, be it C 3, C 4, CAM or any other plants. It occurs in the stroma of chloroplasts. The first product of carbon dioxide fixation is 3 carbon compound … WebC 4 fixation is an addition to the ancestral and more common C 3 carbon fixation. The main carboxylating enzyme in C 3 photosynthesis is called RuBisCO, which catalyses two distinct reactions using either CO 2 (carboxylation) or oxygen (oxygenation) as a substrate.
