What is the final digestion product of proteins by protease?

• A. Nucleotides
• B. Peptides
• C. Amino acids
• D. Glucose

Answer: (C)

Proteases break peptide bonds in proteins to release the building blocks of proteins, amino acids. In digestion, proteins are first cleaved into smaller peptides, but these are then further degraded by other enzymes into free amino acids that can be absorbed by the intestinal lining. Nucleotides come from nucleic acids, not proteins. Peptides are intermediate products, not the final digestion products. Glucose comes from carbohydrate digestion. Therefore, the final digestion product of proteins by protease is amino acids.
