Acid present in gastric juice is_________?
Correct answer: A. Hydrochloric Acid
- A. Hydrochloric Acid
- B. Citric Acid
- C. Sulphuric Acid
- D. Acetic Acid
Explanation
The stomach lining secretes hydrochloric acid, which creates a strongly acidic medium for pepsin activity and helps kill many swallowed microorganisms. Citric acid is found mainly in citrus fruits, while sulphuric and acetic acids are not the normal gastric acid. Students may choose another familiar acid because they confuse acids found in foods with the acid in gastric juice.
