Q. Enzyme nitrogenase is required for :
- Nitrification
- Nitrite reduction
- Nitrate reduction
- Nitrogen fixation
Solution :
Correct option : D Nitrogenase is an enzyme present in legume root roots. It is a highly sensitive enzyme to molecular oxygen required to fix atmospheric nitrogen in leguminous plants. It is made up of Mo-Fe protein and catalyses the conversion of atmospheric nitrogen to ammonia. So the correct answer is ‘Nitrogen fixation’.
