Photorespiration

Vedclass · Answer

(B) Photorespiration is a wasteful process that occurs in $C_3$ plants because the enzyme $RuBisCO$ has an affinity for both $CO_2$ and $O_2$. In $C_3$ plants,when $O_2$ levels are high,$RuBisCO$ binds with $O_2$ instead of $CO_2$,leading to photorespiration. $C_4$ plants have evolved a special mechanism (Kranz anatomy) to concentrate $CO_2$ around the $RuBisCO$ enzyme,which effectively eliminates photorespiration. Therefore,photorespiration is the key physiological difference between $C_3$ and $C_4$ plants.
