When oxygen is absent, the reactions produces less energy than normal, however it is still released from food by braking it down by chemically, and they produce carbon dioxide A common example of anaerobic respiration is within yeast, it is the action of yeast on sugar solution to produce alcohol. The sugar is not completely oxided to carbon dioxide and water but it is converted to alcohol.
