Yeast fermentation is used in brewing and bread-making. Key words Aerobic respiration: Breaking down glucose with oxygen to release energy and producing carbon dioxide and Anaerobic respiration (fermentation): Releasing energy from the breakdown of glucose without oxygen, producing lactic acid (in animals) and ethanol and carbon dioxide (in plants and microorganisms).
