Question

Quizplus · Accepted Answer

The stomach initiates protein digestion through the action of pepsin, which breaks down protein into smaller peptides. The small intestine is the primary site for absorption of nutrients from food, not the stomach. Lipids are primarily digested in the small intestine, not the stomach. Starch is partially broken down by the enzyme amylase in the mouth and then further broken down in the small intestine, not the stomach.
