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.
