Q.
Given below are two statements: [2023]

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:

1 Statement I is correct but Statement II is incorrect.

2 Statement I is incorrect but Statement II is correct.

3 Both statements I and II are correct

4 Both statements I and II are incorrect

Ans.
(3)

Ribulose Bisphosphate Carboxylase-Oxygenase (RuBisCO) is the most abundant protein in the whole of the biosphere. $C_{4}$ plants lack photorespiration as they have a mechanism that increases the concentration of $C O_{2}$ at the enzyme site, so RuBisCO does not bind to oxygen.
