D)nerve impulses

Question

Quizplus · Accepted Answer

Second messengers such as cAMP, PKA, and Ca2+ can influence the sensitivity of postsynaptic receptors to dopamine, norepinephrine, or serotonin by modulating the activity of the receptor and downstream signaling pathways. Antagonists directly block the receptor, neurotransmitters activate the receptor, and nerve impulses trigger the release of neurotransmitters but do not directly adjust the sensitivity of postsynaptic receptors.
