When we breathe, what do we do of the nitrogen contained in the air?
When we breathe, we use the oxygen of the air to oxydize our body sugar or fat to produce energy (via ATP molecules). Water and carbon dioxyde (CO2) are by-products of these reactions. ATP is used by our muscles to move. Water is easily recycled within our body and we finally exhale the CO2. So O2 in, energy and water in the middle and CO2 out.
Now, we don't inhale oxygen, we inhale air which is roughly made of 80% nitrogen, 20% oxygen and a few other molecules in very little quantities. So does our body handle or process the nitrogen in the air, and if so, how ?
