It can bind to both $CO_2$ and $O_2$ depending on their relative concentrations.

Vedclass · Answer

(C) $RuBisCo$ is called $RuBP$ Carboxylase-Oxygenase because it exhibits dual catalytic activity,meaning it can bind to both $CO_2$ and $O_2$. Its function depends on the relative concentration of these two gases:$(i)$ When $CO_2$ concentration is high relative to $O_2$,the enzyme acts as a carboxylase,facilitating the fixation of $CO_2$ with $RuBP$ to initiate the $C_3$ cycle (Calvin cycle),leading to the production of glucose.$(ii)$ When $O_2$ concentration is high relative to $CO_2$,the enzyme acts as an oxygenase,initiating photorespiration ($C_2$ cycle) by binding $RuBP$ with $O_2$ to form phosphoglycolate,which is an energy-consuming process.$(iii)$ In $C_4$ plants,the enzyme is protected from oxygenase activity because they possess a mechanism to concentrate $CO_2$ around the $RuBisCo$ enzyme,ensuring it functions primarily as a carboxylase.

Why is the $RuBisCo$ enzyme more appropriately called $RuBP$ Carboxylase-Oxygenase and what important role does it play in photosynthesis?
