Detailed explanation-1: -CO2 is produced as a byproduct of this reaction. The O2 needed for cellular respiration is obtained via inhalation. The CO2 that is generated is removed from the body via exhalation.
Detailed explanation-2: -The process of respiration produces energy for organisms by combining glucose with oxygen from the air. During cellular respiration, glucose and oxygen are changed into energy and carbon dioxide. Therefore, carbon dioxide is released into the atmosphere during the process of cellular respiration.
Detailed explanation-3: -At ordinary temperatures, carbon dioxide is quite unreactive; above 1, 700 °C (3, 100 °F) it partially decomposes into carbon monoxide and oxygen. Hydrogen or carbon also convert it to carbon monoxide at high temperatures.
