1. Aerobic micro-organisms (aerobes) are those that require oxygen for growth; obligate aerobes cannot survive in the absence of oxygen. The opposite are anaerobic organisms, which do not require oxygen for growth; obligate anaerobes cannot survive in the presence of oxygen.

2. Aerobic exercise is physical activity which requires an increase in heart rate and respiration to meet the increased demand of muscle for oxygen, as contrasted with maximum exertion or sprinting, when muscle can metabolize anaerobically, producing lactic acid, which is metabolized later, creating a need for increased respiration after the exercise has ceased (so-called oxygen debt).

Aerobic as applied to metabolism in cells of the body, or in microorganisms, means oxygen-utilizing. Aerobic metabolism occurs in most animal cells, and depends upon the presence of mitochondria, in which the key chemical processes take place. Aerobic bacteria inhabit the body surface and orifices — they do not have mitochondria. Aerobic exercise is that which is sustainable in balance with oxygen intake — for example, a 10 km race, or any milder rhythmic exercise.
