The function of leghaemoglobin in the root nodules of legumes is:

  1. A
    Inhibition of nitrogenase activity
  2. B
    Oxygen removal
  3. C
    Nodule differentiation
  4. D
    Expression of nif gene

Solution & Step-by-step Explanation

The enzyme nitrogenase is highly sensitive to molecular oxygen. Leghaemoglobin acts as an oxygen scavenger, binding to oxygen to maintain anaerobic conditions within the root nodule, thereby protecting the nitrogenase enzyme.
