Question

What happens to nitrogen during the process of denitrification?

Answer 1

Nitrogen is released in environment.

Explanation:

Throgh the denitrification, the denitrifying bacteria release the gaseous nitrogen into environment. Thanks.

Answer 2

Denitrification is the process by which nitrites or nitrates are reduced to produce nitrogen gas.

Explanation:

Denitrification is a process within the nitrogen cycle.

It is sort of the opposite of nitrogen fixation in the sense that it undoes the results of nitrogen fixation. It is carried out largely by denitrifying bacteria.

Denitrification is the process by which nitrates (`NO_3^-`) are reduced to produce nitrogen gas or dinitrogen (`N_2`). The image below shows the reactions with the enzymes involved included.
