Answer:
Aerobic respiration
Respiration using oxygen to break down food molecules is called aerobic respiration. 'Aero' means air, which contains oxygen, leading to the name aerobic respiration. Glucose is the molecule normally used for respiration - it is the main respiratory substrate. Glucose is oxidised to release its energy, which is then stored in ATP molecules.
Anaerobic respiration
Most organisms cannot respire without oxygen but some organisms and tissues can continue to respire if the oxygen runs out. In conditions of low or no oxygen the process of anaerobic respiration occurs. The 'an' in 'anaerobic' means without.
During anaerobic respiration, the oxidation of glucose is incomplete - not all of the energy can be released from the glucose molecule as it is only partially broken down. The reaction therefore releases much less energy than aerobic respiration - around only a nineteenth of the energy released during aerobic respiration. This means that fewer molecules of ATP can be made.
Glucose in human muscle cells is converted to lactic acid during anaerobic respiration:
glucose → lactic acid (+ ATP made)
The lactic acid is a waste product.
