A) it transports oxygen to the root nodule
B) it acts as an oxygen scavenger
C) it provides energy to the nitrogen fixing bacterium
D) it acts as a catalyst in transamination
Correct Answer: B
Solution :
Leghaemoglobin is red \[{{O}_{2}}\] binding and iron containing protein present in the root nodules. It functions as an oxygen buffer, cycling between the oxidized \[{{(Fe)}^{3+}}\] and reduced \[{{(Fe)}^{2+}}\] forms to keep free \[{{O}_{2}}\] levels within the nodule low. Thus, it acts as an oxygen scavanger and protects the enzyme nitrogenase from being inactivated by oxygen.
