NEET2023BotanyPhotosynthesis in Higher PlantsActual
Given below are two statements : Statement I : RuBisCO is the most abundant enzyme in the world. Statement II : Photorespiration does not occur in C ₄ plants. In the light of the above statements, choose the most appropriate answer from the options given below :
Options
- ABoth Statement I and Statement II are correct
- BBoth Statement I and Statement II are incorrect
- CStatement I is correct but Statement II is incorrect
- DStatement I is incorrect but Statement II is correct
Correct answer
A. Both Statement I and Statement II are correct
Step-by-step solution
Statement-I: RuBisCO is the most abundant enzyme in the world as it is responsible for the first step of C ₃ cycle and found in all photosynthetic organisms. Statement-II: RuBisCO is encaged in bundle sheath cells in C ₄ plants which inhibits its oxygenase activity and thus, inhibits the process of photorespiration. Hence both the statements are correct.
