Vedclass · Answer

(B) Leghaemoglobin is an oxygen scavenger found in the root nodules of leguminous plants. The enzyme nitrogenase,which is responsible for biological nitrogen fixation,is highly sensitive to molecular oxygen $(O_2)$. Leghaemoglobin binds to $O_2$ and maintains a low concentration of free oxygen in the nodules,thereby creating an anaerobic environment that protects the nitrogenase enzyme from oxidative damage and allows it to function efficiently.
