Explain how and where alcohol is metabolized in the body, beginning with absorption into the body and ending with the metabolites of alcohol metabolism
?Alcohol is absorbed into the body in the stomach and small intestines, with some alcohol breakdown beginning in the stomach by stomach alcohol dehydrogenases; however, alcohol can be absorbed directly into the blood stream in the stomach, as well as the small intestines, which allows it to have effects in the body soon after consumption. Once in the bloodstream, alcohol is taken to the liver, which then begins breaking down the alcohol with additional alcohol dehydrogenases in the liver. The first step of breakdown in the liver is to break the alcohol into acetaldehyde. The second step is to convert the acetaldehyde to acetate, which can then be converted to either carbon dioxide or acetyl CoA. Hydrogen ions are also produced, which can then be used in the electron transport chain.
