Mucus contains ______ that help kill bacteria.

Mucus is a protective secretion found in various parts of the body, particularly in the respiratory and digestive tracts. One of its critical components is lysozymes, which are enzymes that have the ability to break down the cell walls of certain bacteria. By hydrolyzing the peptidoglycan layer in bacterial cell walls, lysozymes can effectively kill or inhibit the growth of bacteria, thereby playing a significant role in the body’s defense mechanisms.

While antibodies, other enzymes, and proteins play various roles in the immune response, lysozymes are specifically recognized for their direct antibacterial properties within mucus. This makes them essential for maintaining mucosal health and preventing infections.
