Decarboxylation of $C_4$ acid

Vedclass · Answer

(C) In $C_4$ plants,the $C_4$ acid (malic acid or aspartic acid) is transported to the bundle sheath cells. Inside the bundle sheath cells,this $C_4$ acid undergoes decarboxylation to release $CO_2$. This process increases the intracellular concentration of $CO_2$ around the $RuBisCO$ enzyme. High $CO_2$ concentration ensures that $RuBisCO$ functions primarily as a carboxylase rather than an oxygenase,thereby minimizing photorespiration.
