Question

Quizplus · Accepted Answer

Endorphins are naturally occurring opioids that produce analgesia, or pain relief, and give the feeling of euphoria. Morphine is a synthetic compound that mimics endorphins, making it an agonist. Curare is a drug that paralyzes muscles and has no effect on endorphins, so it is not considered an endorphin agonist or antagonist.
