Question

Find out which on is an incorrect match:

• A. Endopeptidase – Pepsin-like enzyme
  
• B. Exopeptidase – Amylopsin
• C. Pancreatic lipase – Steapsin
• D. Nucleases – Ribonuclease

Answer 1

The correct option is B Exopeptidase – Amylopsin

An exopeptidase is any peptidase that catalyzes the cleavage of the terminal peptide bond. For example, dipeptidases and aminopeptidases. While, amylopsin is a pancreatic enzyme that converts starch to sugar.

Endopeptidase is the proteolytic enzyme that breaks the peptide chain at internal locations. Example pepsin, trpsin, chymotrypsin, etc.

The key difference between endopeptidase and exopeptidase is that the endopeptidase breaks peptide bonds within the protein molecules while the exopeptidase cleaves peptide bonds at the terminals of the protein molecules.

Lipase is an enzyme or a biological catalyst that catalyzes the hydrolysis of the fats or lipids. The pancreatic lipase (also referred to as pancreatic triacylglycerol lipase) is the fat-splitting enzyme secreted by the pancreas.

Nucleases are a class of enzymes in which nucleic acids like RNA and DNA are hydrolyzed.

So, out of the given options, only option B is the incorrect match.
