Lysozyme is an enzyme that
A
inhibits viruses
B
lyses host cells
C
stimulates the immune system
D
is an antibacterial substance
Explanation: 

Detailed explanation-1: -Lysozyme as an enzymatic globular protein has gained great attention in the pharmaceutical and food industries owing to its antibacterial function. As reported, all lysozymes can hydrolyze the -(1, 4)-glycosidic linkages between N-acetylmuramic acid (NAM) and N-acetylglucosamine (NAG) of peptidoglycan chains.

Detailed explanation-2: -Lysozyme is a  14 kDa protein present in many mucosal secretions (tears, saliva, and mucus) and tissues of animals and plants, and plays an important role in the innate immunity, providing protection against bacteria, viruses, and fungi.

Detailed explanation-3: -Antimicrobial enzymes are widespread in nature, where they play a critical role in defending living organisms from bacterial attack. These enzymes are now increasingly being exploited against microbial systems.

Detailed explanation-4: -Lysozyme has been used clinically in the treatment of periodontitis, administered in chewing gum, and implemented to prevent tooth decay. It has also been administered to patients suffering from cancer for its analgesic effect and has been used as a potentiating agent in antibiotic therapy.
