What is a key difference between aerobic and anaerobic respiration in animals?
Anaerobic respiration occurs without oxygen
Aerobic respiration takes place in the presence of oxygen: glucose is broken down completely in the mitochondria into carbon dioxide and water, releasing a large amount of energy (about 38 ATP per glucose).
Anaerobic respiration takes place in the absence of oxygen. In animal muscle cells during heavy exercise, glucose is broken down only partially into lactic acid, releasing much less energy (2 ATP per glucose).
So the main difference is the need for oxygen. Anaerobic respiration releases less energy, not more; aerobic respiration does use glucose; and lactic acid is formed in anaerobic, not aerobic, respiration.
Hence, Anaerobic respiration occurs without oxygen.
