Question

Name the enzyme that helps in nitrogen fixation in living cells

Answer 1

Answer:

Nitrogenase.

Explanation:

Nitrogenase is the enzyme that helps in the fixation of nitrogen. The nitrogenase helps to convert the atmospheric nitrogen into ammonia which can get absorbed by the living cells.

The cell which is having the enzyme nitrogenase is the heterocyst. The nitrogen fixation is a very important phenomenon which is required very much since nitrogen is required by the plant.

Answer 2

The enzyme that helps in nitrogen fixation in living cells is NITROGENASE.

• Nitrogen is present in ample amount in atmosphere. But still, it is not available for biological fixation because plants have no metabolic process that can fix nitrogen.
• This property of converting atmospheric nitrogen into usable forms of living organisms like nitrate, nitrite, ammonia, etc is called nitrogen fixation. And, this is done by nitrogen-fixing bacteria like Rhizobium etc. The principle enzyme helping in nitrogen fixation in these bacteria is the nitrogenase. This enzyme converts atmospheric nitrogen into ammonia.
