Aerobic respiration: Respiration including oxygen. Releases more energy, and has less toxic by-products.
Glucose + Oxygen --> Carbon dioxide + Water
Anaerobic respiration: Respiration without oxygen. Releases less energy than aerobic respiration, and has toxic by-products, e.g. lactic acid in animals, ethanol in plants and yeast.
Glucose --> Carbon dioxide + Lactic acid
Glucose --> Carbon dioxide + Ethanol
