Nitrogenase enzyme convertsa)Nitrate and nitrite into nitrogenb)Atmosp...
Nitrogenase enzyme converts atmospheric nitrogen into ammonia.
Explanation:
Nitrogen is an essential element required for the growth and survival of living organisms. However, the atmospheric nitrogen (N2) is highly stable and cannot be used by most living organisms. Nitrogenase enzyme is responsible for converting atmospheric nitrogen into ammonia (NH3), which can be used by plants and other organisms.
The process of nitrogen fixation involves the following steps:
1. The nitrogenase enzyme complex consists of two key proteins - the nitrogenase reductase and the nitrogenase iron protein.
2. The nitrogenase iron protein binds to atmospheric nitrogen and reduces it to two molecules of ammonia using electrons from the nitrogenase reductase.
3. The process of nitrogen fixation requires a lot of energy and is carried out under anaerobic conditions in specialized cells called heterocysts found in certain types of bacteria and cyanobacteria.
Significance of nitrogen fixation:
1. Nitrogen fixation is essential for the growth and survival of plants and other organisms.
2. It plays a crucial role in maintaining the nitrogen cycle and the balance of nitrogen in the environment.
3. It reduces the need for synthetic fertilizers, which can have negative impacts on the environment.
In conclusion, nitrogenase enzyme is responsible for converting atmospheric nitrogen into ammonia, which is essential for the growth and survival of living organisms.
