The secretory process's ionic needs secretory stimulants may depolarize the membrane of the pancreatic -cell, hence accelerating insulin secretion from the islets of Langerhans. Cholecystokinin (CCK) is produced by neuroendocrine cells in the upper small intestine mucosa. Food molecules, namely proteins and lipids, activate these cells, resulting in the release of CCK into the bloodstream. CCK promotes pancreatic secretion through two different methods. The presence of glucose in the blood stimulates insulin secretion in beta cells. Insulin is released in a dose-dependent manner as circulation glucose levels rise, such as after eating a meal. This kind of release is known as Glucose-Stimulated Insulin Secretion (GSIS).
