Enzyme required in early CO2 fixation in C4 cycle is
A. RuBP carboxylase
B. RuBP oxygenase
C. PEP carboxylase
D. PGA dehydrogenase
Answer: Option C
Solution(By Examveda Team)
The enzyme required in early CO2 fixation in the C4 cycle is PEP carboxylase.PEP carboxylase, which is located in the mesophyll cells, is an essential enzyme in C4 plants.
It is an enzyme in the family of carboxy-lyases found in plants and some bacteria that catalyzes the addition of bicarbonate (HCO3-) to phosphoenolpyruvate (PEP) to form the four-carbon compound oxaloacetate and inorganic phosphate.
