Which neuromodulator is not capable of binding to opiate receptors in the analgesic pathways?

E)enkephalins

Question

Quizplus · Accepted Answer

Bradykinin is a peptide that is involved in pain sensation and inflammation, but it is not an opiate or part of the endogenous opioid system. Therefore, it cannot bind to opiate receptors and is not directly involved in the analgesic pathways that utilize opioids. Dynorphin, endogenous opiates, endorphins, and enkephalins are all capable of binding to opiate receptors in the analgesic pathways and can produce analgesia.
