Question

Quizplus · Accepted Answer

Glucagon is synthesized in the rough endoplasmic reticulum (RER) of pancreatic alpha cells. The RER is involved in the synthesis of proteins, including hormones like glucagon, which are then processed and secreted. Aldosterone, cortisol, and testosterone are steroid hormones synthesized in the smooth endoplasmic reticulum and mitochondria of adrenal and gonadal cells, while calcitriol is a form of vitamin D synthesized in the kidneys, also involving the smooth ER and mitochondria, not the rough ER.
