Is digesting an apple an physical or chemical change?

Answer 1

The digestion of food through the alimentary canal involve a series of chemical and physical changes. In the example of Pizza its bread component undergoes chemical changes as it is digested by amylase enzymes in saliva. Other chemical changes include hydrochloric acid of the stomach "attacking" and digesting proteins found in the pizza.

Answer 2

It is both.

The physical change is in the consistency of the food, and much of it goes into solution in the stomach acid. The chemical change is the stomach acid breaking down the food into digestible components (proteins, carbohydrates, and fats)that can be absorbed and used by the human body.

Chewing (which tears and crushes the food) and the churning function of the stomach are Physical Changes. The reactions of your saliva and stomach acids with the food are Chemical Changes.

Answer 3

Its a Chemical change because the food would be transformed into something different than its physical appearance. Remember, once it involves enzymes in the process it should be considered as a chemical change.
