There is no photorespiration in C4 plants. Explain in your own words​

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.
