Protecting nitrogenase

Vedclass · Answer

(D) The root nodule cells of leguminous plants contain a pink-colored pigment called leghaemoglobin. Nitrogen fixation is catalyzed by the enzyme nitrogenase,which is highly sensitive to oxygen. Leghaemoglobin acts as an oxygen scavenger,creating an anaerobic environment within the nodule to protect the nitrogenase enzyme from oxidative damage,thereby ensuring efficient nitrogen fixation.
