Vedclass · Answer

(D) Photorespiration is a wasteful process that occurs in $C_3$ plants when the enzyme RuBisCO acts as an oxygenase rather than a carboxylase.This process is stimulated by conditions that favor the oxygenase activity of RuBisCO.$1$. High temperature: As temperature increases,the affinity of RuBisCO for $CO_2$ decreases more rapidly than for $O_2$.$2$. High $O_2$ concentration: $A$ high ratio of $O_2$ to $CO_2$ promotes the binding of $O_2$ to the active site of RuBisCO.$3$. High light intensity: High light intensity often leads to increased internal $O_2$ levels due to rapid photolysis of water and increased temperatures,which indirectly stimulates photorespiration.Therefore,all the given factors contribute to the stimulation of photorespiration.
