Question

Quizplus · Accepted Answer

HCl in the stomach performs all three functions: it kills bacteria, breaks down the connective tissue of meat, and activates pepsin from pepsinogen. The acidity of the stomach (pH ~ 2) is necessary for pepsinogen to be converted into the active enzyme pepsin, which is responsible for breaking down proteins in the stomach. HCl also helps in creating an acidic environment which kills most of the bacteria that enter the stomach with food.
