Suppose scientists develop a new, highly addictive drug called PxH.Based on what you know about the effect of drugs on neural activity, which of the following is most likely to be true about PxH?
A)PxH can be distinguished from naturally occurring neurotransmitters in the synapse.
B)PxH permanently disables the production of new neurotransmitters.
C)PxH operates via mechanisms that are independent from neurotransmitters.
D)PxH mimics neurotransmitters and binds to receptors.

Question

Quizplus · Accepted Answer

Highly addictive drugs, like PxH, typically operate by mimicking neurotransmitters and binding to receptors. This enhances neural activity, which can lead to addiction. Therefore, option D is the most likely to be true about PxH. Option A is incorrect, as addictive drugs often resemble naturally occurring neurotransmitters, making them difficult to distinguish from each other. Option B is incorrect, as drugs usually do not permanently disable the production of new neurotransmitters. Option C is incorrect, as drugs typically operate via mechanisms that involve neurotransmitters in some way.
