Answer:
Digestive system breakdown small proteins into amino acids by chemical digestion using enzymes (option B).
Explanation:
One of the main functions of the digestive system is to degrade food to facilitate its absorption at the intestinal level. This degradation has a mechanical phase, which includes chewing and contracting the stomach, and an enzymatic phase.
The enzymes that allow the breakdown of proteins into amino acids are called proteases, or peptidases. They are enzymes capable of breaking peptide bonds, obtaining at the end amino acids that can be more easily assimilated by the organism.
<em>The other options are not correct because </em><u><em>mechanical digestion</em></u><em> reduces the size of the digested food and mixes it with the gastric juices, but does not break the peptide bonds.</em>
