Vedclass · Answer

(B) The enzyme responsible for nitrogen fixation is $Nitrogenase$. $Nitrogenase$ is highly sensitive to the presence of oxygen $(O_2)$. Oxygen inactivates the $Nitrogenase$ enzyme,thereby inhibiting the process of biological nitrogen fixation. Therefore,nitrogen-fixing bacteria,such as $Rhizobium$,create an anaerobic (oxygen-free) environment (often using $Leghemoglobin$) to protect the enzyme and allow the fixation process to occur.

The process of nitrogen-fixation by bacteria does not take place in the presence of
