anaerobic
anaerobic Applying to metabolism in the cells of the body, or to micro-organisms, this means functioning without oxygen. Examples include anaerobic glycolysis: the pathway of hexose breakdown from glucose 6-phosphate to lactate in muscle, and the main component of the metabolism of red blood cells, which have no mitochondria. Anaerobic bacteria inhabit the lower part of the intestines. Applying to exercise: more intense than can be maintained in balance with oxygen intake, aerobic pathways being insufficient to supply energy at the required rate (though they always contribute as well) — as in a 200-metre sprint.
Neil C. Spurway See exercise; lactate threshold; metabolism. |

anaerobic
anaerobic Connected with the absence of oxygen or air, or not dependent on oxygen or air for survival. An anaerobic organism (anaerobe), such as a bacterium or yeast, is a microorganism that can survive by releasing energy from glucose and other foods in the absence of oxygen. The process by which it does so is called anaerobic respiration. It differs from aerobic respiration, in which an organism must have oxygen to release energy. Most anaerobes can survive in oxygen but do not need it for respiration.

anaerobic
anaerobic
1. Of an environment: one in which air (oxygen) is absent. In the case of a depositional environment, one with 0.0–0.1 ml of dissolved oxygen per litre of water. Compare AEROBIC; and DYSAEROBIC. 2. Of an organism: one able to grow only in the absence of oxygen, i.e. an anaerobe. 2. Of a process: one that can occur only in the absence of oxygen. |

anaerobic
anaerobic
1. Of an environment: one in which oxygen is absent. 2. Of an organism: one able to exist only in the absence of oxygen, i.e. an anaerobe. Organisms may be facultative anaerobes (e.g. yeasts) or obligatory anaerobes (e.g. sulphur bacteria). 3. Of a process: one that can occur only in the absence of oxygen. |
