प्रश्न
With regard to the Biological Nitrogen Fixation by Rhizobium in association with soybean, which one of the following statement/ statements does not hold true.
पर्याय
Nitrogenase may require oxygen for its functioning
Nitrogenase is MO- Fe protein
Leg-hemoglobin is a pink coloured pigment
Nitrogenase helps to convert N2 gas into two molecules of ammonia
उत्तर
Nitrogenase may require oxygen for its functioning
Explanation:
Nitrogenase is highly sensitive to molecular oxygen (O2) and thus requires anaerobic conditions. Nodules have adaptations that ensure that the enzyme is protected from O2. To protect nitrogenase, the nodule contains an O2-scavenger celled leghaemoglobin.
