Nitrate is needed for protein metabolism.
The energy needed for metabolism comes from the food you eat. That is why unhealthy food slows down the metabolism.
One cannot help but inhale a certain amount of nitrogen with every breath, due to its high concentration in the air. However, nitrogen is not used as extensively by the body as oxygen, and thus most of what is inhaled is then exhaled back into the atmosphere. Oxygen is used all the time in cellular respiration, while nitrogen is less commonly needed.
There is no nitrogen in glucose.
Nitrogen is needed because it cools down things and also nitrogen keeps the earth from over heating.
The relationship is when the cellular respiration takes CO2 through the plants system it helps bring what is needed for photosynthesis to occur.
