Quizplus · Accepted Answer

MAO (monoamine oxidase) is an enzyme that breaks down neurotransmitters such as dopamine and serotonin. Chronic smokers have been shown to have lower levels of MAO, leading to decreased breakdown of dopamine. This can result in higher levels of dopamine in the brain, which may contribute to addiction and other smoking-related behaviors. Therefore, the correct answer is D, breaking down levels of dopamine.
