Respiration

In the process of respiration, first, the gaseous exchange happens at the lungs level, followed by breathing, gas transport by blood, then gaseous exchange at tissue level, and finally, cellular respiration.

This equation represents the process of respiration, where glucose (C H O ) reacts with oxygen to produce carbon dioxide, water, and energy. This is a key process in the metabolism of living organisms.

Step 1: Inhaled Air.
In atmospheric air, the concentration of carbon dioxide is approximately 0.03\%. Step 2: Exhaled Air.
During respiration, carbon dioxide concentration increases in exhaled air and reaches around 4.4\%. Step 3: Conclusion.
Hence, inhaled air contains 0.03\% and exhaled air contains 4.4\%.
