Question

Do humans use nitrogen?

Answer 1

Hint: Nitrogen is the chemical element and present in the atmosphere in the form of nitrogen gas. The atmosphere contains 78 % nitrogen only. Nitrogen also has a big role in the human metabolic reactions.

Complete answer:
- In the question it is asked do humans use nitrogen.
- Yes humans need nitrogen, without nitrogen human body metabolism does not exist.
- But the humans are unable to take the nitrogen from the atmosphere directly.
- Because in the atmosphere nitrogen exists in dimeric form and contains a triple bond in it.
- Humans can digest the nitrogen because of the presence of the triple bond.
- Therefore the humans are going to take the nitrogen from the plants and from small living organisms.
- The plants and bacteria convert atmospheric nitrogen to nitrates and nitrites, this process is called nitrogen fixation.
 -In the human body all the proteins contain nitrogen, all the nucleotides in the genetic material nitrogen is present.
- Humans will take nitrogen form the primary food chain and utilize it for different purposes in the human body.
- Therefore humans need nitrogen.

Note:
Nitrogen belongs to p –block and is present in V th group in the periodic table. Nitrogen has a big role in human metabolism. If there is any deficiency of nitrogen then human metabolism stops work. Without the involvement of nitrogen we cannot imagine human life. Nitrogen is not present in its purest form it is present in the form of its derivatives in the human body.
