Lysozyme vs. Lysosome: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Lysozyme is an enzyme that breaks down bacterial cell walls, while a lysosome is an organelle in cells containing digestive enzymes.
Key Differences
Lysozyme is an enzyme found in various bodily fluids like saliva and tears, known for its ability to break down the cell walls of bacteria, thus playing a crucial role in the immune response. On the other hand, lysosomes are membrane-bound organelles within cells, essential for intracellular digestion and the breakdown of cellular waste and debris.

The function of lysozyme is specific to attacking bacterial infections by hydrolyzing the peptidoglycan layer of bacteria. In contrast, lysosomes contain a variety of digestive enzymes that degrade all kinds of biomolecules including proteins, lipids, and nucleic acids.

Lysozyme is significant in providing innate immunity and is one of the body's first lines of defense against infection. In comparison, lysosomes are involved in numerous cellular processes, including autophagy, where they help in the degradation and recycling of cellular components.

A deficiency or malfunction in lysozyme can lead to increased susceptibility to bacterial infections. Conversely, lysosomal storage diseases occur when lysosomes fail to properly digest cellular materials, leading to an accumulation of toxic substances in the cells.

Lysozyme can be found in many secretions including mucus, saliva, and tears, where it acts as an antimicrobial agent. Lysosomes, found in almost every animal cell, are known as the cell’s “garbage disposal,” breaking down excess or worn-out cell parts.
