Aerobic respiration requires oxygen from the air, whereas anaerobic respiration does not. Aerobic produces Carbon dioxide and water, and the carbon dioxide exits through a gas exchange system in humans. Anaerobic respiration produces lactic acid and no carbon dioxide. Aerobic respiration produces a large amount of energy, whereas anaerobic respiration produces a small, quick burst of energy. The oxidation of glucose is complete in aerobic and incomplete in anaerobic respiration.
