Contrast the terms agonist and antagonist using acetylcholine as an example.
What will be an ideal response?
An agonist is a chemical that mimics or enhances the function of a neurotransmitter at its receptors, while an antagonist is a chemical that reduces the effects of a neurotransmitter at its receptors. For example, nicotine and muscarine act like acetylcholine at the nicotinic and muscarinic acetylcholine receptors, respectively. The plant toxin curare acts as an antagonist at nicotinic acetylcholine receptors, which is why this toxin produces paralysis.
