Question

Quizplus · Accepted Answer

The stomach secretes hydrochloric acid and the enzyme pepsinogen, which is converted to the active enzyme pepsin in the presence of acid. Pepsin is responsible for breaking down proteins into smaller polypeptides. Starch digestion primarily begins in the mouth with the enzyme amylase, while fat digestion takes place primarily in the small intestine with the assistance of bile. Disaccharides are broken down into monosaccharides by enzymes in the small intestine. Vitamins do not require chemical digestion, but rather are absorbed through various mechanisms in the small intestine.
