Hydrochloric acid in the stomach does not only make the medium acidic. What is another important function?
Answer and explanation
Correct answer: Killing germs that enter with food
The governing concept is the protective and digestive role of gastric hydrochloric acid. Food may carry microbes into the stomach, and the strongly acidic medium destroys or inhibits many of them. The acid also provides the conditions needed for pepsin to digest proteins. Thus option A is correct. Oxygen binding is performed by haemoglobin, light capture by chlorophyll, and urine storage by the urinary bladder, not by stomach acid.
