Question

Which gas prevents nitrogen fixation?

Answer 1

Answer:

Nitrogenases gas prevents nitrogen fixation. Biological nitrogen fixation or BNF can be formed during the atmospheric nitrogen process and atmopstheric nitrogen can be converted to ammonia by an enzyme. This enzyme is known as Nitrogenases.

Answer 2

Oxygen prevents nitrogen fixation.

Explanation:

Nitrogenase enzyme is used in nitrogen fixation which reduces in its quality while coming in contact with the oxygen and thus interrupts the fixation process. Through nitrogen fixation, nitrogen molecules are converted into ammonia and other nitrogenous components of soil.

It is required for biosynthesis of nitrogen compounds in different organisms. But oxygen degrades the nitrogenase which results in interrupted production of different enzymes and hence prevents the fixation.
