What is the final step in the metabolism of alcohol?

A) Ethanol production
B) Aldehyde production
C) The production of carboxylic acids
D) The production of carbon dioxide and water

The final step in the metabolism of alcohol involves its conversion into carbon dioxide and water, which are then excreted from the body. This process occurs after alcohol is first converted into acetaldehyde (an aldehyde) and then into acetic acid (a carboxylic acid) before finally being broken down into carbon dioxide and water.
