Answer: Protease is an enzyme which causes break down of proteins by converting them into smaller polypeptides or amino acids.
Explanation:
Proteases are the enzymes that are necessary for the functioning of the lungs. They cause the regeneration and repair of white blood cells as protease can digest connective tissue elements. They are responsible for generating an inflammation response during infection caused by a pathogen. Thus prevents lung infection. Inhibition of the anti-proteolytic mechanism is essential for the controlling microbial infection and lung inflammation.
