Is photorespiration present at low light intensity in c3 and c4 plants? Is photorespiration present at high light intensity in c3 and c4 plants?

Expert Answer

Photorespiration only occurs under high light intensities.
It also requires high temperatures and high oxygen levels to occur.
In C₄ plants, the process does not occur.
In C₃ plants, if the intensity of light is high and O₂ levels are high along with high temperature, photorespiration is likely to occur.
