Answer:
The role of enzymes in the small intestine during protein digestion is to split proteins into amino acids and small peptides (option C).
Explanation:
Protein digestion consists of the enzyme-mediated process that converts ingested proteins into simple compounds that are easily absorbed by the intestine.
The enzyme that promotes protein digestion is produced in the pancreas and is called protease. Proteases act in the small intestine and convert proteins into amino acids and small peptides that can be absorbed by the body.
The other options are not correct because.
<em> A. Carbon-carbon double bonds do not come from protein digestion.
</em>
<em> B. Not only oligopeptides come from protein digestion.
</em>
<em> D. Enzymes and hormones are specialized proteins.</em>
