WebMar 18, 2024 · C4 plants—including maize, sugarcane, and sorghum—avoid photorespiration by using another enzyme called PEP during the first step of carbon fixation. This step takes place in the mesophyll cells that are located close to the stomata where carbon dioxide and oxygen enter the plant. WebCarbon is primarily fixed through photosynthesis, but some organisms use a process called chemosynthesis in the absence of sunlight. Organisms that grow by fixing carbon are called autotrophs, which include photoautotrophs (which use sunlight), and lithoautotrophs (which use inorganic oxidation).

WebC-4 photosynthesis is photosynthesis used for specific C-4 plants, and instead of producing a 6-carbon molecule as its first product, it produces a 4-carbon molecule. Photorespiration is used when a plant can't get enough CO2 for normal photosynthesis, so it uses O2, and this process later releases CO2. 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.

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.
