Vedclass · Answer

(B) The enzyme nitrogenase,which is responsible for biological nitrogen fixation,is highly sensitive to molecular oxygen $(O_2)$.In the root nodules of leguminous plants,the enzyme nitrogenase requires an anaerobic environment to function effectively.Leghaemoglobin is a pink-colored pigment present in the root nodules that acts as an oxygen scavenger.It binds to oxygen with high affinity,thereby maintaining a low concentration of free $O_2$ in the nodule,which protects the nitrogenase enzyme from oxidative damage and ensures its optimal activity.
