Question

Which of the following process will be affected by the absence of enterokinase?

• A. Lipid $\to$ Fatty acid + Glycerol
• B. Dipeptides $\to$ Amino acid
• C. Proteoses $\to$ Dipeptide
• D. Amylose $\to$ Maltose

Answer 1

Answer: (B)

Dipeptides $\to$ Amino acid

A trypsinogen is a precursor form of trypsin. Trypsin is involved in the breakdown of proteins. It cleaves the peptide bond of a polypeptide to yield amino acids. The inactivated form trypsinogen is activated by enterokinase. It is produced by the duodenum. It converts trypsinogen to trypsin. The absence of enterokinase will lead to the absence of an active form of the enzyme, trypsin which is involved in the conversion of dipeptides to amino acids.

Thus, the correct option is option B.
