One painkilling drug that locks into the same receptor sites as endorphins is ________.

Question

Quizplus · Accepted Answer

Endorphins are neurotransmitters that naturally bind to opioid receptors, reducing pain signals in the body. Morphine is a potent pain-relieving drug that works by mimicking endorphins and binding to the same opioid receptors, effectively blocking pain signals and producing a sense of relief. Barbiturates, neuroleptics, and beta-blockers do not bind to opioid receptors and are not effective painkillers.
