If a researcher reports a significant increase in neurotransmitter turnover after administering a drug,then:
A) the drug likely increased calcium influx.
B) the drug likely decrease release of the neurotransmitter.
C) an increase in drug reuptake likely occurred.
D) the drug likely increased release of the neurotransmitter.

Question

Quizplus · Accepted Answer

If there is a significant increase in neurotransmitter turnover, it means that there has been an increase in the rate at which neurotransmitters are released and degraded. The most likely explanation for this is that the drug increased the release of the neurotransmitter. Option A is incorrect because calcium influx is typically involved in neurotransmitter release, but not necessarily in the context of a drug administration. Option B is incorrect because a decrease in neurotransmitter release would cause a decrease in turnover, not an increase. Option C is also incorrect because an increase in drug reuptake would decrease neurotransmitter turnover, not increase it.
