Given below are two statements :
Statement I : RuBisCO is the most abundant enzyme in the world.
Statement II : Photorespiration does not occur in $\mathrm{C}_4$ plants.
In the light of the above statements, choose the most appropriate answer from the options given below :
Both Statement I and Statement II are correct
Both Statement I and Statement II are incorrect
Statement I is correct but Statement II is incorrect
Statement I is incorrect but Statement II is correct
Solution
Statement-I: RuBisCO is the most abundant enzyme in the world as it is responsible for the first step of $\mathrm{C}_3$ cycle and found in all photosynthetic organisms.
Statement-II: RuBisCO is encaged in bundle sheath cells in $\mathrm{C}_4$ plants which inhibits its oxygenase activity and thus, inhibits the process of photorespiration.
Hence both the statements are correct.
