The enzyme that catalyses carbon dioxide fixation in C4 plants is
A. RuBP carboxylase
B. PEP carboxylase
C. Carbonic anhydrase

Answer: Option B
Solution(By Examveda Team)
The enzyme that catalyzes carbon dioxide fixation in C4 plants is PEP carboxylase.PEP carboxylase, which is located in the mesophyll cells, is an essential enzyme in C4 plants.
In hot and dry environments, carbon dioxide concentrations inside the leaf fall when the plant closes or partially closes its stomata to reduce water loss from the leaves.
