All of the answer choices are involved in digestion. Chewing breaks down food into smaller pieces, allowing for easier swallowing and increasing surface area for chemical digestion. Churning and mixing in the stomach continues to break down food and mix it with digestive enzymes and acids. Chemical digestion involves the breakdown of large molecules into smaller, absorbable molecules through the use of enzymes and other molecules. Enzymes specifically break down proteins into amino acids for absorption.
