Statement-I: RuBisCO is the most abundant enzyme in the world as it is responsible for the first step of C3 cycle and found in all photosynthetic organisms. Statement-II: RuBisCO is encaged in bundle sheath cells in C4 plants which inhibits its oxygenase activity and thus, inhibits the process of photorespiration. Hence both the statements are correct.
Given below are two statements : Statement I : RuBisCO is the most abundant enzyme in the world. Statement II : Photorespiration does not occur in…
