Answer:
Alcohol dehydrogenase (ADH)
Step-by-step explanation:
Alcohol metabolism starts in the stomach with the release of of an enzyme known as alcohol dehydrogenase by the liver. The enzyme is released into the stomach and helps in the catabolic reaction that eventually sees the conversion of alcohol to acetaldehyde.
The acetaldehyde produced in the first reaction is further broken down into acetate by another enzyme known as aldehyde dehydrogenase (ALDH). Thereafter, the produced acetate undergoes further reactions to produce water and carbon-dioxide.
The answer is alcohol dehydrogenase (ADH).
