Affect of CO2 on photosynthesis : Carbon dioxide acts as a major limitin factor for photosynhesis. The CO2 is 0.03 % in atmosphere and increase in amount of CO2 upto 0.05% in atmosphere increases the rate of photosynthesis. Beyond it the rate declines. It is due to the increase in the temperature.
The C3 and C4 plants responds differently o the CO2 concentration. The C3 plants respond to a higher concentration of CO2 by showing increased rates of photosynthesis while the C4 plants saturate at low level of CO2 and do not show increase in the rate of photosynthesis.
Name the pentose phosphatew which is a CO2 acceptor in the dark reaction of photosynthesis ?
