$RuBP$ - carboxylase

Vedclass · Answer

(C) In $CAM$ (Crassulacean Acid Metabolism) plants,$CO_2$ fixation occurs in two stages. During the night,$CO_2$ is fixed by $PEP$ carboxylase to form oxaloacetate,which is then converted to malic acid and stored in the vacuole. During the day,the stored malic acid is decarboxylated to release $CO_2$ inside the cell. This released $CO_2$ is then fixed by the $RuBP$ carboxylase (Rubisco) enzyme in the Calvin cycle. Therefore,the $CO_2$ fixation that occurs during the day in the mesophyll cells is mediated by $RuBP$ carboxylase.

In the mesophyll cells of $CAM$ plants,$CO_2$ fixation during the day occurs via:
