Question

chapter 14 end of chapter review question 9 1 part -- of 1 point which receptor pairing below is correct? nicotinic: acetylcholine muscarinic: norepinephrine alpha 1: acetylcholine nicotinic: norepinephrine check answer

Explanation:

To determine the correct receptor - neurotransmitter pairing, we analyze each option:

• Nicotinic receptors are cholinergic receptors, meaning they bind to acetylcholine. This is a well - established fact in the study of the autonomic nervous system and neurophysiology.
• Muscarinic receptors also bind to acetylcholine, not norepinephrine (norepinephrine binds to adrenergic receptors).
• Alpha - 1 receptors are adrenergic receptors and bind to norepinephrine (or epinephrine), not acetylcholine.
• As established earlier, nicotinic receptors bind to acetylcholine, not norepinephrine.

So, the correct pairing is nicotinic with acetylcholine.

Answer:

A. nicotinic: acetylcholine
