Why does not photorespiration take place in C4 plants? -Biology

Description : Why does not photorespiration take place in C4 plants? -Biology

Last Answer : Photorespiration occurs due to the oxygenase activity of RuBisCO. When the concentration of O2 is high, RuBisCO binds to oxygen and carries out photorespiration. C4 plants have a mechanism of maintaining high CO2 concentration at the enzyme site, thus photorespiration does not occur
