• A. Scavanging of oxygen
• B. Nodule formation
• C. Help reduction of nitrite
• D. None of the above

Answer 1

The correct option is A Scavanging of oxygen

Leg-haemoglobin pigment plays a very important role in the process of nitrogen fixation. The enzyme system, which is responsible for nitrogen fixation in root nodule bacteria is highly sensitive to oxygen. The pigment leg-haemoglobin binds oxygen and thus protects the nitrogen fixing enzymes.

So, the correct answer is 'Scavanging of oxygen'
