In cellular respiration, carbon dioxide is formed from the oxidation of glucose molecule.
Respiration is also called energy releasing process. In respiration, oxygen is inhaled through the air into the body which combines with glucose which is present inside the cells. This combination of oxygen and glucose produces carbondioxode, water and energy in the form of Adenine tri phosphate (ATP). Carbondioxode removed from the body through lungs and ATP is used for different processes.
