प्रश्न
When we breathe in air, nitrogen also goes inside along with oxygen. What is the fate of this nitrogen?
विकल्प
It moves along with oxygen into the cells
It comes out with the CO2 during exhalation
It is absorbed only by the basal cells
Nitrogen concentration is already more in the cells so it is not at all absorbed.
उत्तर
It comes out with the CO2 during exhalation
Explanation:
Nitrogen is an inert gas and is not used as such by the human body. About 78% of atmospheric air contains nitrogen gas and % the age of nitrogen in exhaled air is also 78%. Nitrogen gas is not absorbed by any molecule in the human body and is exhaled as such in the environment. Elemental nitrogen which is an essential component of the human body is consumed in other fixed forms like NH4 ions, amino acids, etc.
