Detailed explanation-1: -Carbon dioxide and water are created as byproducts. The overall equation for aerobic cellular respiration is: In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.
Detailed explanation-2: -Aerobic respiration breaks down glucose and combines the broken down products with oxygen, making water and carbon dioxide. The carbon dioxide is a waste product of aerobic respiration because cells do not need it.
Detailed explanation-3: -Thus three times carbon dioxide is released during the course of aerobic respiration-once during oxidative decarboxylation of pyruvate and two during the Krebs or citric acid cycle.
Detailed explanation-4: -Carbon atoms are removed from the organic molecule (glucose) to form carbon dioxide. Aerobic respiration involves the complete combustion of glucose (6C) – so six CO2 molecules are produced.
Detailed explanation-5: -Glycolysis produces zero molecules of carbon dioxide.
