Obligate aerobes Notes:
An obligate aerobe is an organism that requires oxygen to grow. Through cellular respiration, these organisms use oxygen to metabolize substances, like sugars or fats, to obtain energy. For example most eukaryotic organisms produce energy in this way including humans. In this type of respiration, oxygen serves as the terminal electron acceptor for the electron transport chain. Aerobic respiration has the advantage of yielding more energy (adenosine triphosphate or ATP) than fermentation or anaerobic respiration, but obligate aerobes are then also subject to high levels of oxidative stress. Examples of obligately aerobic bacteria include and Mycobacterium tuberculosis.
