Question

The acid produced in the stomach a) Hcl b) Kcl c) NaCl d) BrCl2​

Answer 1

• The mucosa of the stomach has gastric glands.

      The oxyntic cells of gastric glands secrete HCl and intrinsic factors.

• HCl is important because the proenzyme pepsinogen gets converted into pepsin on exposure to hydrochloric acid. Pepsin is the proteolytic enzyme of the stomach, it converts protein into smaller units called proteases and peptones.

• Hydrochloric acid provides acidic pH of about 1.8 which is optimal for the functioning of pepsin.

The correct answer will be option a.

Answer 2

• As we know that the mucosa of the stomach has gastric glands.
• So, The oxyntic cells of gastric glands secrete HCl and intrinsic factors.
• And as we know HCl is important because the proenzyme pepsinogen gets converted into pepsin on exposure to hydrochloric acid.
• So, this Pepsin is the proteolytic enzyme of the stomach, it converts protein into smaller units called proteases and peptones.
• And this Hydrochloric acid provides acidic pH of about 1.8 which is optimal for the functioning of pepsin.

Hence, we get the correct answer will be an option a.
