Question

Enzymes that attack the peptidoglycan layer of the bacteria and are present in perspiration, nasal secretion, saliva and tear are:

1) Amylase
2) Lipase
3) Protease
4) Lysozyme

Answer 1

The enzyme that attacks the peptidoglycan layer of bacteria and is found in various secretions such as perspiration, nasal secretion, saliva, and tears is lysozyme. This enzyme is part of the body's innate immune system and targets bacterial cell walls specifically.

Step-by-step explanation:

The enzymes that attack the peptidoglycan layer of bacteria and are found in perspiration, nasal secretion, saliva, and tear are not amylase, lipase, or protease, but rather the enzyme lysozyme. Lysozyme is a crucial part of the body's innate immune system, helping to protect against bacterial infections by breaking down the cell walls of bacteria, particularly targeting the peptidoglycan layer. Unlike proteases, which can target various proteins, or amylase and lipase, which digest starches and fats respectively, lysozyme is specifically designed to combat bacterial infections.
