Final answer:
Beta-endorphin is produced from the same prohormone as adrenocorticotropin (ACTH), which stimulates the adrenal cortex to secrete corticosteroid hormones.
Step-by-step explanation:
Beta-endorphin is produced from the same prohormone as adrenocorticotropin (ACTH). ACTH stimulates the adrenal cortex to secrete corticosteroid hormones, including cortisol. Both beta-endorphin and ACTH are produced from a precursor molecule known as pro-opiomelanocortin (POMC).
