Question

Alcohol not metabolised is changed into

• A. Butanol
• B. Butyric acid
• C. Acetic acid
• D. Acetaldehyde

Answer 1

The correct option is D Acetaldehyde

Oxidative pathways are by far the main pathways responsible for ethanol clearance. The Microsomal Ethanol Oxidizing System (MEOS) system catalyzes the oxidation from ethanol to acetaldehyde, coupling this reaction to the oxidation of an NADPH molecule, and the reduction of an oxygen molecule to form hydrogen peroxide. Mitochondria participate with the conversion of acetaldehyde into acetate and the generation of increased amounts of NADH.

So the correct answer is 'Acetaldehyde'.
