← Human Body & HealthWhich neurological consequence results when agonist drugs disrupt normal neurotransmitter reuptake?
A)Sustained postsynaptic receptor stimulation✓
B)Rapid neurotransmitter enzymatic inactivation
C)Reduced action potential propagation velocity
D)Inhibition of vesicular neurotransmitter synthesis
💡 Explanation
Sustained postsynaptic receptor stimulation occurs because agonist drugs block neurotransmitter reuptake. This leads to increased synaptic neurotransmitter concentration and prolonged receptor binding, therefore extending the postsynaptic effect, rather than processes like enzymatic deactivation.
