Afterall C4 are more efficient than C3 as they lack photorespiration. However complex carbohydrates raise blood sugar rapidly whereas simple carbohydrates (e.g. When almost all the CO2 is utilized there will be much higher quantity of O2 compared to CO2. C. photosynthesis is carried out by two photosystems that work best at a wavelength of 690 nm. C 4 photosynthesis has a number of distinct properties that enable the capture of CO 2 and its concentration in the vicinity of Rubisco, so as to reduce the oxygenase activity of Rubisco, and hence the rate of photorespiration. One advantage is that such a habitat is less exposed to the vagaries of weather and climate. Job email alerts. 8 0 obj How much deuterium is in the plant determines its pH. They use c4 mechanism.
