nitrogen fixing bacteria

Vedclass · Answer

(B) Nitrogen-fixing bacteria,such as $Rhizobium$,possess an enzyme called nitrogenase which is responsible for the fixation of atmospheric nitrogen into ammonia. This enzyme is highly sensitive to oxygen and is inactivated in its presence. Therefore,these bacteria require an anaerobic environment (oxygen-free) to function effectively,often provided by the protein leghemoglobin in root nodules.
