aerobic

views updated

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.
