What are the two enzymes responsible for the breaking down of alcohol?

Alcohol dehydrogenase and aldehyde dehydrogenase
Cytochrome P450 and catalase
Alcohol oxidase and acetaldehyde dehydrogenase
Ethanol dehydrogenase and methanol dehydrogenase

The correct answer is: Alcohol dehydrogenase and aldehyde dehydrogenase

Alcohol dehydrogenase and aldehyde dehydrogenase are the two enzymes responsible for breaking down alcohol. These enzymes are found in the liver and are crucial for breaking down alcohol into less harmful byproducts. Option B, Cytochrome P450 and catalase, are enzymes responsible for drug metabolism and oxidative stress responses, but not specifically for the breakdown of alcohol. Option C, alcohol oxidase and acetaldehyde dehydrogenase, are not present in humans and are instead found in bacteria and yeasts. Option D, ethanol dehydrogenase and methanol dehydrogenase, are not specific enzymes for the breakdown of alcohol and their main function is the breakdown of other types of alcohols. Therefore, A is the correct choice.
