Endorphins are similar in chemical structure to which drug?

Question

Quizplus · Accepted Answer

Endorphins are similar in chemical structure to heroin. Heroin is an opioid drug that binds to receptors in the brain, producing feelings of pain relief and pleasure. Endorphins also bind to these same receptors, but they are produced naturally by the body in response to pain, exercise, or other triggers. This is why endorphins are often referred to as the body's natural painkillers.
