Stomach.

Kidneys.

Liver.

Blood.

Previous problemNext problem

Verified step by step guidance

Understand that alcohol metabolism primarily involves the enzyme alcohol dehydrogenase (ADH), which catalyzes the conversion of ethanol to acetaldehyde.

Recall that while some alcohol metabolism can occur in the stomach lining, the majority of alcohol processing by ADH takes place in a specific organ responsible for detoxification and metabolism.

Identify the liver as the main organ where alcohol dehydrogenase is highly active and where most alcohol is metabolized.

Recognize that the kidneys are primarily involved in filtering blood and excreting waste, not in metabolizing alcohol via ADH.

Conclude that the liver is the correct answer because it contains the highest concentration of alcohol dehydrogenase and is the central site for alcohol metabolism.
