PEP carboxylase
I. is involved in atleast some fixation in both and plants
II. Catalyses the reaction of fixing into pyruvic acid in bundle sheath cells
III. is capable of fixing more efficiently at lower atmospheric concentration than RuBP carboxylase
Select the correct option
I. is involved in atleast some fixation in both and plants
II. Catalyses the reaction of fixing into pyruvic acid in bundle sheath cells
III. is capable of fixing more efficiently at lower atmospheric concentration than RuBP carboxylase
Select the correct option
View answer and explanation
Correct option: D
Only III
The correct answer is D (Only III) because PEP carboxylase is more efficient at lower CO2 concentrations than RuBP carboxylase.
