Detoxification by the liver hinges on hepatocytes using specialized enzymes to transform xenobiotics into more water-soluble forms for excretion. The liver carries out two linked steps: Phase I reactions, often via cytochrome P450 enzymes, introduce or reveal functional groups; Phase II reactions then conjugate these substances with glucuronic acid, sulfate, glutathione, or other groups. This broad system handles a wide range of drugs and toxins, including alcohol, not just one substance. The other statements don’t fit because the liver doesn’t detoxify bile, which is a secretion, and it doesn’t detoxify oxygen—oxygen is used in metabolic reactions rather than detoxified.
