    Reference: AQA

    Respiration that takes place without oxygen, occurs in the cytoplasm, and partially breaks down glucose, transferring less energy per glucose molecule because glucose is not fully oxidised.
    AQA · Aerobic and anaerobic respiration (study guide)
    Respiration that takes place in muscles when insufficient oxygen is supplied, breaking down glucose without oxygen and releasing less energy per glucose molecule.
    AQA · Response to exercise (study guide)
    Respiration that supplements aerobic respiration when oxygen supply is insufficient, causing lactic acid to build up.
    AQA · Response to exercise (study guide)
    Occurs without oxygen and transfers much less energy per glucose molecule than aerobic respiration.
    AQA · Aerobic and anaerobic respiration (study guide)
    Respiration in animals that produces lactic acid and releases less energy per sugar molecule.
    AQA · Active transport (study guide)
    Respiration that does not require oxygen and produces lactic acid (in animals) or ethanol and carbon dioxide (in yeast/plants), releasing a small amount of energy.
