Multiple Choice

Which molecule is produced directly by dipeptidases?

Dipeptidases cleave the bond inside a dipeptide to yield amino acids. So the molecule produced directly is amino acids. Dipeptides are the substrates they act on, not the products, and nucleic acids are unrelated to this enzymatic step. In digestion, after dipeptides and small peptides are formed, dipeptidases release amino acids that can be absorbed.
