Vedclass · Answer

(A) Photorespiration is a wasteful process that occurs in $C_3$ plants when the enzyme $RuBisCO$ acts as an oxygenase rather than a carboxylase.This happens primarily under conditions of high $O_2$ concentration and low $CO_2$ concentration.Additionally,high temperatures favor the oxygenase activity of $RuBisCO$.Therefore,an excess amount of $O_2$ relative to $CO_2$ is the primary condition that triggers photorespiration.
