Both the esophagus and the small intestine are involved in the digestion of food. The esophagus squeezes food into the stomach by wave-like muscle contractions. Peptidase enzymes in the small intestine break food molecules into smaller molecules. Which statement best describes changes to food during digestion? O The muscle contractions result in physical changes, while the action of the peptidase results in chemical changes. O The muscle contractions and the action of the peptidase both result only in physical changes. O The muscle contractions result in chemical changes, while the action of the peptidase results in physical changes. O The muscle contractions and the action of the peptidase both result only in chemical changes.
