$A$ and $R$ are correct.

Vedclass · Answer

(A) The enzyme nitrogenase,which is responsible for biological nitrogen fixation,is highly sensitive to molecular oxygen $(O_2)$.It requires anaerobic conditions to function effectively.In root nodules of leguminous plants,the enzyme leghaemoglobin acts as an oxygen scavenger.It creates an anaerobic environment by binding to oxygen,thereby protecting the nitrogenase enzyme from oxidative damage.Therefore,both statement $A$ and statement $R$ are correct.

$A -$ The enzyme nitrogenase is highly sensitive to molecular oxygen.
$R -$ To protect nitrogenase enzymes,the nodule contains an oxygen scavenger called leghaemoglobin.
