A) cotinine.
B) choline.
C) acetaldehyde.
D) MAO.

Question

Quizplus · Accepted Answer

Biotransformation of nicotine primarily produces cotinine, which has similar pharmacological effects to nicotine and is also addictive. Choline is the precursor to the neurotransmitter acetylcholine and is not a product of nicotine metabolism. Acetaldehyde is a toxic byproduct of alcohol metabolism and is not directly involved in nicotine metabolism. MAO (monoamine oxidase) is an enzyme that helps to break down neurotransmitters like dopamine and serotonin, but it is not a metabolite of nicotine.
