Hydrochloric acid is secreted into the stomach by __<\/strong> cells. Oa. zymogenic Ob. parietal Oc. chief Od. beta<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The correct answer is Ob. parietal<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

Hydrochloric acid (HCl) is secreted by parietal cells<\/strong> in the stomach lining. These cells are located primarily in the gastric glands, which are found within the mucosal layer of the stomach. Parietal cells play a crucial role in the digestive process by producing HCl, which serves several important functions in the stomach:<\/p>\n\n\n\n

    \n
  1. Acidic Environment for Digestion<\/strong>: The hydrochloric acid lowers the pH of the stomach contents, which activates pepsinogen (an inactive enzyme precursor) to pepsin, an enzyme that helps break down proteins into smaller peptides.<\/li>\n\n\n\n
  2. Protection Against Pathogens<\/strong>: The acidic environment also helps kill harmful microorganisms that may have been ingested with food, protecting the body from infections.<\/li>\n\n\n\n
  3. Facilitates Nutrient Absorption<\/strong>: HCl helps to dissolve minerals such as calcium and magnesium, aiding in their absorption later in the digestive process.<\/li>\n\n\n\n
  4. Activation of Intrinsic Factor<\/strong>: Parietal cells also produce intrinsic factor, a glycoprotein essential for the absorption of vitamin B12 in the small intestine.<\/li>\n<\/ol>\n\n\n\n

    To summarize, the parietal cells are responsible for secreting hydrochloric acid, contributing significantly to digestion and overall stomach function.<\/p>\n\n\n\n

    Incorrect Options:<\/h3>\n\n\n\n
      \n
    • Oa. zymogenic cells<\/strong> (also known as chief cells<\/strong>) produce pepsinogen, which is converted into pepsin when activated by the acidic environment created by parietal cells.<\/li>\n\n\n\n
    • Oc. chief cells<\/strong> are responsible for the secretion of pepsinogen, not hydrochloric acid.<\/li>\n\n\n\n
    • Od. beta cells<\/strong> are located in the pancreas and are responsible for secreting insulin, which regulates blood glucose levels.<\/li>\n<\/ul>\n\n\n\n

      Thus, parietal cells<\/strong> are the correct answer when it comes to secreting hydrochloric acid into the stomach.<\/p>\n\n\n\n
