Low $CO_2$ concentration and high temperature

Vedclass · Answer

(B) $C_4$ plants are superior to $C_3$ plants under conditions of low $CO_2$ concentration and high temperature.$(i)$ $C_4$ plants possess a specialized anatomy called Kranz anatomy,which allows them to concentrate $CO_2$ around the enzyme RuBisCO,minimizing photorespiration.$(ii)$ They utilize the enzyme $PEP$ carboxylase,which has a high affinity for $CO_2$ and is insensitive to $O_2$,preventing the wasteful process of photorespiration that occurs in $C_3$ plants.$(iii)$ Because they avoid photorespiration,$C_4$ plants maintain high photosynthetic efficiency even in hot and dry environments where $CO_2$ levels might be limiting.
