Whats the difference between aerobic and anaerobic metabolism?

Anaerobic (without o2) = the creation of energy through the burning of carbohydrates in the absence of oxygen (Glucose = lactic acid, Fats = ketoacids) Aerobic (with o2) = the creation of energy through the burning of carbohydrates, amino acids, and fats in the presence of oxygen Protein= amino acids, Fats = fatty acids, Phosphorus = phosphoric acid)
