What effect would a drug that blocks a membrane transporter for a neurotransmitter likely have?
A) Increased synthesis of the neurotransmitter
B) Increased storage of neurotransmitters in vesicles
C) Increased levels of the neurotransmitter in the synaptic cleft
D) Increased release of the neurotransmitter

Question

Quizplus · Accepted Answer

Blocking a membrane transporter for a neurotransmitter would likely lead to increased levels of the neurotransmitter in the synaptic cleft. This is because the transporter normally removes excess neurotransmitter from the cleft and brings it back into the presynaptic neuron or glial cell. Blocking the transporter would prevent this removal, resulting in higher concentrations of the neurotransmitter in the cleft.
