Which best describes the role of nitrogen in the human body

You did not give the answer choices however... It is used to make amino acids in our body which in turn make proteins. It is also needed to make nucleic acids, which form DNA and RNA. Human or other species on earth require nitrogen in a ‘fixed’ reactive form. Human can’t utilise nitrogen through respiration, but can absorb through the consumption of plants or animals that have consumed nitrogen rich vegetation. The air we breathe is around 78% nitrogen, so it is obvious that it enters our body with every breath. This nitrogen helps in protein synthesis, amino acids that influence growth, hormones, brain functions and the immune system. Hope that helps. Brainliest m!
