Answer
The peptidoglycan present in the bacterial cell wall begins to degrade when contacting with lysozyme. Thus lysozyme prevents bacterial infections.
Work Step by Step
Lysozyme is one of the antimicrobial enzymes generated by animals and forms the innate immune system in the body. This enzyme secretes tears, saliva, human milk, etc. When bacteria contact with lysozyme, the peptidoglycan present in the bacterial cell wall begins to degrade. This eventually kills the bacteria. Thus lysozyme prevents bacterial infections.
