Lízózyomok are specialized organelles found in eukaryotic cells, serving as the primary sites for intracellular digestion. These spherical vesicles are enclosed by a single membrane and are filled with a variety of hydrolytic enzymes. These enzymes are capable of breaking down a wide range of biomolecules, including proteins, nucleic acids, carbohydrates, and lipids. The acidic environment within the lysosome, maintained by proton pumps in the membrane, is optimal for the activity of these enzymes.

Lízózyomok play a crucial role in cellular housekeeping, removing waste materials and cellular debris through a process called autophagy. They engulf and degrade damaged or aged organelles, ensuring the cell's internal environment remains clean and functional. Furthermore, lysosomes are involved in phagocytosis, the process by which cells engulf external particles such as bacteria or other foreign substances. The lysosome then fuses with the phagosome containing the ingested material, and its enzymes break down the foreign matter, contributing to the cell's defense mechanisms. Deficiencies or malfunctions of lysosomal enzymes can lead to a class of genetic disorders known as lysosomal storage diseases, where undigested materials accumulate within cells, causing significant cellular and organismal damage.
