BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The digestion of protein starts in the stomach, where HCl and pepsin break proteins into smaller polypeptides, which then travel to the small intestine (Figure 3).

Detailed explanation-2: -The stomach releases gastric juices containing hydrochloric acid and the enzyme, pepsin, which initiate the chemical digestion of protein.

Detailed explanation-3: -This is the process where complex molecules like proteins, fats, and carbohydrates are broken down into smaller pieces that your body can use. It requires special proteins called enzymes.
