WebThe acid conditions in the stomach serve a number of functions: Assists in the digestion of food (by dissolving chemical bonds within food molecules) Activates stomach proteases (e.g. pepsin is activated when pepsinogen is proteolytically cleaved in acid conditions) Prevents pathogenic infection (stomach acids destroy microorganisms in ingested ... WebJan 17, 2024 · The secretion of pepsinogen prevents self-digestion of the stomach cells. Gastric acid kills most of the bacteria in food, stimulates hunger, and activates pepsinogen into pepsin; it also denatures the complex protein molecule as a precursor to protein digestion. Goblet cells produce mucus that protects the stomach from self-digestion.
WebHydrochloric acid: This component helps to maintain the acidic pH of the stomach, which is important for the activation of pepsinogen into pepsin. It also helps to kill any ingested bacteria or other pathogens that might be present in the food. Pepsinogen: This is an inactive enzyme that is produced by the chief cells in the stomach.
