What percentage of alcohol is metabolized by the liver?

The liver is the primary organ responsible for metabolizing alcohol in the human body. It breaks down approximately 90-98% of the alcohol consumed, with the most widely accepted figure being around 95%, making it the correct choice in this context. The remaining percentage of alcohol is metabolized through other means, such as excretion in breath, sweat, and urine.

This high percentage reflects the liver's essential role in detoxifying alcohol. The metabolic process involves enzymes such as alcohol dehydrogenase (ADH), which converts ethanol into acetaldehyde, and then further into acetic acid, which is eventually transformed into carbon dioxide and water for elimination from the body.

Additionally, factors like individual metabolism, overall health, and drinking patterns can affect exact figures, but the general understanding in the context of alcohol metabolism is that the liver handles the vast majority of it.
