  1. Question 1

    Q1. Which mechanism is primarily responsible for the oxidation of acetone by the enzyme acetyl-CoA dehydrogenase?

    • A) Oxidative decarboxylation to produce carbon dioxide and water
    • B) Reductive amination to produce NADH and ammonia
    • C) Beta-oxidation to produce acetyl-CoA and NADH
    • D) Alpha-oxidation to produce glyoxylate and NADH

    Answer: Beta-oxidation to produce acetyl-CoA and NADH

    Explanation: Beta-oxidation is primarily responsible for the oxidation of acetone. It fails because oxidative decarboxylation is primarily involved in the breakdown of other aldehydes.
