Chief cells produce pepsinogen, while parietal cells secrete hydrochloric acid (HCl) in the stomach for protein digestion.
Chief cells, located in the gastric glands of the stomach, release pepsinogen, an inactive precursor enzyme. Pepsinogen is converted to its active form, pepsin, by the acidic environment in the stomach. Pepsin plays a vital role in breaking down proteins during digestion. Parietal cells, also present in the gastric glands, are responsible for secreting hydrochloric acid (HCl).
This strong acid serves several crucial functions in the stomach. It activates pepsinogen to pepsin, facilitating protein digestion. Additionally, HCl creates the highly acidic environment necessary for pepsin's action and further protein breakdown. Moreover, the acidic conditions in the stomach help sterilize the contents, neutralize harmful microorganisms, and enable the absorption of certain nutrients.
