WebC 4 photosynthesis requires the integrated functioning of mesophyll and bundle-sheath cells of leaves and is characterized by a CO 2 concentrating mechanism that allows Rubisco, located in the bundle-sheath cells, to function at high CO 2 concentrations. 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. sts ardianetWebC4 photosynthesis requires the integrated functioning of mesophyll and bundle-sheath cells of leaves and is characterized by a CO2 concentrating mechanism that allows Rubisco, … sts annual meeting 2017
