Question

The pigments essential for $N_2$ fixation by leguminous plants is leghaemogiobin

• A. True
• B. False

Answer 1

The correct option is A True

• Leghaemoglobin is an oxygen carrier and hemoprotein found in the nitrogen-fixing root nodules of leguminous plants.
• Leghaemoglobin reduce the amount of free oxygen, and thereby to protect the nitrogen-fixing enzyme nitrogenase, which is irreversibly inactivated by oxygen.
• Hence The pigments essential for $N_2$ fixation by leguminous plants is leghaemoglobin is a true statement.
• So, the correct answer is 'True'.
