. A protease is added to a suspension of egg protein in a test-tube and kept at 37°C. After 8 minutes, the protein changes from cloudy to transparent. Which product, or products, will now be present in the test-tube

amino acids

Explanation:

A protease is an enzyme capable of catalyzing the breakdown of proteins into polypeptide fragments and single amino acids, which are the building block of proteins. Proteases act by breaking peptide bonds by a process called hydrolysis, a reaction where water molecules break down peptide bonds (hydro means water and lysis means split). Proteases can be classified depending on the catalytic residue into cysteine, serine, threonine, aspartic, glutamic and metalloproteases.
