प्रश्न
Name the most crucial enzyme found in root nodules for N2 fixation? Does it require a special pink coloured pigment for its functioning? Elaborate.
उत्तर
Nitrogenase is the essential enzyme found in root nodules for nitrogen fixation. It requires a pink-coloured pigment called leghaemoglobin. Leghaemoglobin works as an oxygen scavenger and thus creates anaerobic conditions in the root nodule of a legume. Nitrogenase is highly sensitive to oxygen and needs anaerobic conditions to maintain its existence.
