With the equation of cellular respiration C₆H₁₂O₆ + 6O₂ → 6CO₂+ 6H₂O, gaseous exchange takes place, glucose reacts with oxygen forming Adenosine Triphosphate used by cells.

About 21% of oxygen and 0.4% of carbon dioxide of air is inhaled while the air we breathe out contains 16.4% of oxygen and 4.4% of carbon dioxide because cells use oxygen inhaled to release energy and carbon dioxide as byproduct.

<h3>How does Cellular Respiration work?</h3>

Cellular respiration is how organisms convert fuel into energy and nutrients by combining oxygen with food molecules, sending the chemical energy for life sustaining activities while expelling carbon dioxide and water.

We inhale 21% of oxygen and 0.4% of carbon dioxide and exhale 16.4% of oxygen and 4.4% of carbon dioxide as by product during the process of cellular respiration.
