Nitrogenase is insensitive to oxygen.

(D) The enzyme nitrogenase is highly sensitive to molecular oxygen and requires anaerobic conditions to function effectively. Leghaemoglobin acts as an oxygen scavenger to protect the nitrogenase enzyme from oxygen damage,creating an anaerobic environment within the root nodules. Therefore,the statement that nitrogenase is insensitive to oxygen is incorrect.
