Vedclass · Answer

(B) In the root nodules of leguminous plants,the process of biological nitrogen fixation is carried out by the enzyme nitrogenase. Nitrogenase is highly sensitive to molecular oxygen $(O_2)$ and is inactivated in its presence. To protect the enzyme from oxygen,the root nodules contain a specialized oxygen-scavenging pigment called leghemoglobin. Leghemoglobin creates an anaerobic environment within the nodules,which is essential for the optimal activity of nitrogenase during $N_2$ fixation.

Which pigment is essential for $N_2$ fixation in plants of the family Leguminosae?
