BBH 143 1) The mechanism of alcohol occurs through absorption, distribution, and oxidation. Once swallowed, 20% of the alcohol is absorbed into the stomach while the rest is absorbed in the small intestine. Many factors affect the rate at which the alcohol is absorbed such as the concentration of alcohol, the amount of alcohol, the stomach contents, rates of drinking, body weight, and body chemistry. The alcohol is distributed throughout the body and is eventually combined with oxygen. This process of oxidation results in the formation of water and carbon dioxide and the production of heat and energy. First, alcohol dehydrogenase breaks down the alcohol in the stomach before it enters the blood stream. Then in the liver, alcohol dehydrogenase also acts as a catalyst in changing more of the alcohol into the toxic substance acetaldehyde which is then rapidly oxidized to form acetic acid. The GABA receptors are also a part of this mechanism. They are responsible for inhibiting other neurotransmission and keeping other systems in check. However, alcohol binding facilitates
