Verified step by step guidance

Begin by understanding the process of alcohol metabolism in the human body, which primarily occurs in the liver.

Identify the key enzymes involved in the breakdown of alcohol. The first enzyme is alcohol dehydrogenase (ADH), which converts ethanol into acetaldehyde.

Recognize the role of acetaldehyde in the metabolism process. Acetaldehyde is a toxic compound that needs to be further metabolized.

Introduce the second enzyme, aldehyde dehydrogenase (ALDH), which converts acetaldehyde into acetate, a less harmful substance that can be further processed by the body.

Understand that amylase, lipase, pepsin, trypsin, lactase, and sucrase are not involved in alcohol metabolism. These enzymes are responsible for the digestion of carbohydrates, fats, and proteins, respectively.
