Q35 / 200 · NEET 2023 (Manipur) · Botany

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 :

  • Correct answer
    A
    Both Statement I and Statement II are correct
  • B
    Both Statement I and Statement II are incorrect
  • C
    Statement I is correct but Statement II is incorrect
  • D
    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.

Hence, the correct answer is option: 'A'.
