Oxidation, the burning of alcohol, takes place in which organ?

Explanation:
Alcohol oxidation happens mainly in the liver. This organ contains enzymes like alcohol dehydrogenase that begin the process by turning ethanol into acetaldehyde, and aldehyde dehydrogenase that then converts acetaldehyde into acetate. These reactions use NAD+ and produce NADH, shifting the cell’s redox state and directing the body’s metabolism toward processing the alcohol. The stomach can do a bit of this metabolism, but the liver does the bulk of it, while the kidneys and lungs are not the primary sites for oxidizing ethanol.
