Detailed explanation-1: -Carbon dioxide is produced in the body as a result of cellular respiration, wherein vital nutrients are converted into energy in the presence of oxygen.
Detailed explanation-2: -Cellular respiration converts ingested nutrients in the form of glucose (C6H12O6) and oxygen to energy in the form of adenosine triphosphate (ATP). CO2 is produced as a byproduct of this reaction. The O2 needed for cellular respiration is obtained via inhalation.
