What are the differences in energy metabolism between aerobes and anaerobes?

Aerobes are organisms that live in the presence of oxygen; anaerobes – exist in an oxygen-free environment.

Energy metabolism consists of three stages: preparatory, glycolysis and respiration (oxygen stage). The first stage takes place in animals in the digestive system; the second stage of energy metabolism is in the cytoplasm of cells; the oxygen stage is in the special organelles of the cell – mitochondria.

In anaerobes, energy metabolism is characterized by the first two stages; for aerobes – all three stages.
