Which of the following is a non-microsomal metabolic reaction?

  1. Oxidation of drugs by CYP3A4
  2. Glucuronide conjugation by UGT enzymes
  3. Oxidation by alcohol dehydrogenase
  4. Aromatic hydroxylation by CYP1A2
Show answer and explanation

Correct answer: Oxidation by alcohol dehydrogenase

Non-microsomal enzymes are located in the cytosol, mitochondria, or plasma rather than the smooth ER. Alcohol dehydrogenase and monoamine oxidase (MAO) are key examples of non-microsomal metabolic enzymes.
