Vedclass · Answer

(D) $C_4$ plants are distinguished from $C_3$ plants primarily by the absence of photorespiration in the former.Photorespiration is a light-dependent process involving the oxygenation of ribulose bisphosphate $(RuBP)$ and the release of carbon dioxide by photosynthetic organs.In $C_3$ plants,at high temperatures and high oxygen concentrations,the enzyme $RuBP$ carboxylase acts as an oxygenase,leading to the oxidation of photosynthetic products into $CO_2$ and $H_2O$ without producing useful energy ($ATP$ or $NADPH$).$C_4$ plants have evolved a mechanism to concentrate $CO_2$ around the enzyme,thereby suppressing photorespiration.Peroxisomes and mitochondria are essential organelles for completing the photorespiratory pathway.
