Some proteolytic enzymes are:A. Trypsin, erepsin, pepsinB. Amylopsin, steapsin, proteaseC. Amylase, lipase, zymaseD. Urease, zymase, dehydrogenase

Proteolytic enzymes are enzymes that break down proteins into smaller peptides or amino acids. The correct answer from the given options is:

A. Trypsin, erepsin, pepsin

These enzymes are well-known proteolytic enzymes involved in protein digestion:

Trypsin is produced in the pancreas and acts in the small intestine.
Erepsin is a mixture of proteolytic enzymes found in the small intestine.
Pepsin is produced in the stomach and acts in the acidic environment of the stomach.
The other options include enzymes that are not primarily involved in protein digestion:

Amylopsin (another name for pancreatic amylase), steapsin (another name for pancreatic lipase), and protease (general term for any enzyme that breaks down proteins) in option B.
Amylase (breaks down starch), lipase (breaks down fats), and zymase (a complex of enzymes involved in fermentation) in option C.
Urease (breaks down urea), zymase (as mentioned, involved in fermentation), and dehydrogenase (involved in oxidation-reduction reactions) in option D.
