Aerobic organism
An aerobic organism or aerobe is an organism that has an oxygen based metabolism. Aerobes, in a process known as cellular respiration, use oxygen to oxidize substrates (for example sugars and fats) in order to obtain energy.
- Obligate aerobes require oxygen for aerobic cellular respiration.
- Facultative aerobes can use oxygen, but also have anaerobic methods of energy production.
- Microaerophiles are organisms that may use oxygen, but only at low concentrations.
- Aerotolerant organisms can survive in the presence of oxygen, but they are anaerobic because they do not use it as a terminal electron acceptor.
