Question
The first step in the metabolism of alcohol is its conversion to
Group of answer choices
- formaldehyde.
- acetaldehyde.
- acetic acid.
- aldehyde dehydrogenase.
- wine
Solution
The first step in the metabolism of alcohol (ethanol) involves its conversion into acetaldehyde. This process occurs primarily in the liver and is facilitated by the enzyme alcohol dehydrogenase.
When ethanol is consumed, it is metabolized by alcohol dehydrogenase, which catalyzes the oxidation of ethanol to acetaldehyde. Acetaldehyde is a toxic compound that can cause various adverse effects and is further metabolized into acetic acid by another enzyme, aldehyde dehydrogenase. The acetic acid can then enter the citric acid cycle for energy production.
In summary, the correct answer to the query is acetaldehyde, as it is the immediate product formed during the first step of alcohol metabolism.
