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.
Respiration that takes place in muscles when insufficient oxygen is supplied, breaking down glucose without oxygen and releasing less energy per glucose molecule.
Respiration that supplements aerobic respiration when oxygen supply is insufficient, causing lactic acid to build up.
Occurs without oxygen and transfers much less energy per glucose molecule than aerobic respiration.
Respiration in animals that produces lactic acid and releases less energy per sugar molecule.
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.
