Two protein-digesting enzymes secreted during digestion:

The question specifically asks for protein-digesting enzymes, so do not include salivary amylase (digests starch) or lipase (digests fats).

Note that intestinal juice also converts proteins to amino acids, but the question asks for named enzymes with named glands; pepsin + gastric glands and trypsin + pancreas are the clearest, textbook-stated pairs.
