Quizplus · Accepted Answer

Hydrochloric acid and pepsin are the two substances in the stomach that participate in the chemical digestion of protein. Hydrochloric acid lowers the pH of the stomach, creating an acidic environment that denatures the proteins and makes them more accessible to enzymatic digestion. Pepsin is a digestive enzyme that breaks down proteins into smaller peptides.
