Explanation on page no.203 of Chapter 12 (Mineral nutrition),NCERT book Class XI, under the heading ‘nodule formation’
The enzyme nitrogenase is a Mo-Fe protein and catalyses the conversion of atmospheric nitrogen to ammonia,the first stable product of Nitrogen fixation. This enzyme is highly sensitive to the molecular oxygen; it requires anaerobic conditions. The nodules have adaptations that ensure that the enzyme is protected from oxygen. To protect these enzymes the nodule contains an oxygen scavenger called leg-haemoglobin.It is interesting to note that these microbes live as aerobes under free living conditions (where nitrogenase is not operational),but during nitrogen fixing events,they become anaerobic.
