WebIntroduction. Glucagon-like peptide-1 (GLP-1) is encoded by the proglucagon (GCG) gene in the intestinal L cells. GLP-1 secretion is induced by nutrients in the control of blood glucose and food intake. 1 GLP-1 decreases blood glucose through multiple mechanisms, which includes the promotion of glucose-induced insulin secretion from the pancreatic β cells.

WebSecretin primarily functions to neutralize the pH in the duodenum, allowing digestive enzymes from the pancreas (e.g., pancreatic amylase and pancreatic lipase) to function optimally. [22] Secretin targets the pancreas; pancreatic centroacinar cells have secretin receptors in their plasma membrane. WebThese cells secrete a bicarbonate-rich mucus that coats and lubricates the gastric surface, and serves an important role in protecting the epithelium from acid and other chemical insults. Acid: Hydrochloric acid is secreted from parietal cells into the lumen where it establishes an extremely acidic environment.

WebMechanism of HCl formation: 1. H+ ions are formed inside parietal cells from dissociation of carbonic acid which is formed from combination of CO2 and water under the influence of carbonic anhydrase enzyme (HCO3⁻conc.
