Protein is a macronutrient that we get from food. It is made up of Carbon, Hydrogen, Oxygen, and Nitrogen. Proteins are the body's only source of nitrogen. When we ingest a protein containging food we excrete the nitrogen in our urine; it is called urea.

∙ 8y agoThe atmosphere contains Nitrogen right? The way we get Nitrogen is that the Nitrogen gets absorbed into the ground and it turns into Nirates. Plants contains Nirates and then an animal eats the plants. We eat the animals and that's how we get Nitrogen in our bodies.bleah bleah hehe

∙ 14y agoThe liver produces small amounts of ammonia in deamination reactions. Some of this ammonia provides the nitrogen needed for the synthesis of nonessential amino acids. The liver quickly combines any remaining ammonia with carbon dioxide to make urea, a less toxic compound. The liver releases the urea into the bloodstream and it is take up and excreted by the kidneys.

When does nitrogen leave the air?
Nitrogen leaves the air when lightening strikes, which fixes nitrogen into the soil. Also, nitrogen-fixing plants like legumes have nodules of nitrogen-fixing bacteria in their roots.
How does nitrogen enter and leave the four main spheres?
maybe
Is nitrogen used by the body?
it goes through your body and comes out as carbon dioxide. trees use the carbon dioxide to make more nitrogen that you breathe again.
Does the air we breathe out contains more or less nitrogen?
The nitrogen is not absorbed in your body via lungs. So the amount of nitrogen in inhaled and exhaled air has to be same. Nitrogen protects your body from the harmful effects of 100 % oxygen.
What percentage of nitrogen in human body?
It is made up of 3% nitrogen.
How does nitrogen leave an animals body?
their waste
How much nitrogen in the body?
The human body is about 3% Nitrogen
When an organism dies the nitrogen in its body do what?
the nitrogen in its body is released by the action of decomposers
What is it called when nitrogen taken into the body exceeds nitrogen losses?
negative nitrogen balance.
When nitrogen taken into the body exceeds nitrogen losses a person is in?
Positive nitrogen balance
When does nitrogen leave the air?
Nitrogen leaves the air when lightening strikes, which fixes nitrogen into the soil. Also, nitrogen-fixing plants like legumes have nodules of nitrogen-fixing bacteria in their roots.
What is the important role of nitrogen in the human body?
The human body needs nitrogen for the proper digestion of food and growth. Nitrogen is extremely important in the development of the human fetus.
Which parts of the human body that contain nitrogen?
Most of the nitrogen in your body is contained within proteins and most of the protein in your body is contained within the muscles.
What is nitrogen in the air used for in your body?
Your body is not capable of directly using the nitrogen in air. It is ultimately the source of the nitrogen in the proteins and other nitrogen-containing compounds in your body, but the precursors for these are (mostly) made by nitrogen-fixing bacteria in the soil and then incorporated into molecules by plants. (The "mostly" is because some of the nitrogen used by plants comes from nitrates or ammonia applied as fertilizer.)
Name at least one source of nitrogen for the body?
groundnut is a source of nitrogen.
Where are nitrogen atoms used to build your body?
Nitrogen is an essential part of proteins.
How does your body use nitrogen?
Then Nitrogen you inhale has no use. But nitrogen, from other sources, such as food, helps sperm production.
