Increased synthesis of propiomelanocortin would lead to greater activation of opioid receptors by:
A) norepinephrine.
B) dynorphin A.
C) beta-endorphin.
D) met-enkaphalin.

Question

Quizplus · Accepted Answer

Beta-endorphin is an endogenous opioid peptide derived from propiomelanocyte cells. Its synthesis and release are stimulated by increased activity in the hypothalamic-pituitary-adrenal (HPA) axis, which is the same activation pathway for opioid receptors. Thus, increased synthesis of beta-endorphin would lead to greater activation of opioid receptors.
