Question

Both the stomach and the small intestine are involved in the digestion of food.
The churning of food by stomach muscles and peptidase enzymes in the small
intestine both break food molecules into smaller molecules.
Which statement best describes changes to food during digestion?

Answer 1

Answer: I think the answer is The muscle contractions result in physical changes, while the action of the peptidase results in chemical changes.

Explanation: Because the muscles would make the food smaller and the enzymes have a chemical change to it because it changes the molecules in the food.

Answer 2

The chemical processes in food digestion results in the formation of new

substances.

The statement that best describes the changes in food during digestion is;

The churning of the food is a physical process, which results in physical changes while the peptidase results in chemical changes of the food.

Reasons:  

The given processes in the digestion of food are;

Stomach: Food churning is the process by which the small intestine vigorously turns ingested food.

Small intestine: The action of the peptidase enzyme is to increase the rate of the digestion of food.

Therefore;

The churning of the food is a physical process, which results in physical changes while the peptidase results in chemical changes of the food.
