Why photorespiration does not occur in C 4 plants?

Since C 4 acid from the mesophyll is broken down in the bundle cells to release CO 2 , photorespiration does not occur in C 4 plants, resulting in an increase in the intracellular CO 2 concentration. As a result, the RuBisCO acts as a carboxylase, reducing the oxygenase activity. As a result, the RuBisCO acts as a carboxylase, reducing the oxygenase activity. Despite the fact that Rubisco is responsible for the vast majority of organic carbon on the planet's atmosphere.
