Answer & Solution
Correct Answer:
Option
B
In sugarcane, 14CO2 is fixed in malic acid. The enzyme is PEP carboxylase.
Phosphoenolpyruvate carboxylase 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.
This reaction is used for carbon fixation in CAM and C4 organisms, as well as to regulate flux through the citric acid cycle in bacteria and plants.
