Activation of 5HT_1A serotonin receptors can result in all of the following except a(n) A) increase in Na⁺ conductance across the cell membrane. B) reduction in cAMP synthesis. C) increase in K⁺ conductance. D) decrease in firing of the serotonergic neuron.

Question

Quizplus · Accepted Answer

Activation of 5HT1B/1D serotonin receptors results in a reduction of Na+/Ca2+ conductance across the cell membrane, which leads to inhibition of neurotransmitter release. It also results in a reduction in cAMP synthesis and an increase in K+ conductance, leading to hyperpolarization of the neuron and a decrease in firing. Therefore, option A is incorrect.
