Quizplus · Accepted Answer

Curare inhibits or blocks the action of the neurotransmitter acetylcholine at its receptor channels, which means it binds to the receptor site and prevents ACh from binding and exerting its effects. This classifies curare as an antagonist, which opposes or blocks the action of a neurotransmitter or other agonist molecule.
