Answer:

Protein is broken down into amino acids in the stomach

Explanation:

As you may already know, digestion is the biological process that allows the foods you eat to undergo chemical and physical changes that allow your body to absorb nutrients, minerals, amino acids and all the substances needed by your body.

Physical modifications are responsible for breaking down food into smaller pieces, basically. However, chemical changes are primarily responsible for transforming food into assimilable substances. An example of chemical transformation occurs when protein is broken down into amino acids in the stomach.
