Vedclass · Answer

(C) $C_4$ plants are more efficient in photosynthesis than $C_3$ plants because they have evolved a mechanism to minimize photorespiration.In $C_3$ plants,the enzyme RuBiSCO can bind to $O_2$ instead of $CO_2$ under certain conditions,leading to photorespiration,which consumes energy and releases $CO_2$ without producing sugars.$C_4$ plants utilize a specialized anatomy called Kranz anatomy and a $CO_2$ concentrating mechanism that ensures RuBiSCO always operates in a high $CO_2$ environment.This effectively eliminates photorespiration,allowing for higher rates of carbon fixation and greater production of carbohydrates.

In the $C_4$ cycle,more food (carbohydrates) is produced compared to the $C_3$ cycle. The reason is:
