Question

Which enzyme is capable of nitrogen reduction?

Answer 1

The nitrogenase enzyme is capable of nitrogen reduction.

Nitrogenase enzyme:

1. This enzyme is required to fix atmospheric nitrogen (N≡N). It is made up of Mo-Fe protein.
2. It catalyzes the conversion of atmospheric nitrogen to ammonia.
3. Reduction of inert atmospheric nitrogen to ammonia by living organisms is called biological nitrogen-fixation.
4. Only certain prokaryotic organisms (some bacteria and cyanobacteria) are capable of fixing N₂ . Such microbes are called N₂ -fixers.
5. These N₂ -fixing microbes contain an exclusive enzyme, Nitrogenase.
