Question

Do humans need nitrogen?

Answer 1

Nitrogen requirement:

1. Nitrogen is an important element for survival.
2. All life depends on nitrogen, which is also a necessary component of amino acids, the building blocks which are used to create various hormones, enzymes, and tissues in both animals and humans.
3. To create the proteins found in our muscles, skin, blood, hair, nails, and DNA, our body needs nitrogen.
4. However, humans cannot use nitrogen in the air directly, and instead, need to consume plants and animals to get a sufficient amount of nitrogen.
5. The foods in our diet contain protein that provide us with nitrogen.
