Lysosome
An organelle containing digestive enzymes
Lysosomes are membrane-bound organelles that are found in almost all eukaryotic cells. They are responsible for the breakdown and recycling of cellular waste materials and the breakdown of foreign materials that enter the cell.
Lysosomes contain hydrolytic enzymes such as proteases, nucleases, and lipases that are capable of breaking down proteins, nucleic acids, and lipids into their constituent building blocks. These enzymes are activated only in the acidic environment of the lysosome, which is maintained by a proton pump on the lysosomal membrane.
The process of lysosomal digestion begins with the formation of a digestive vacuole or phagosome, which fuses with a lysosome to form a phagolysosome. The hydrolytic enzymes in the lysosome break down the macromolecules and foreign materials within the phagosome, releasing the breakdown products for reuse by the cell.
In addition to their role in cellular waste disposal, lysosomes also play important roles in cell death, inflammation, and autophagy (the process of breaking down and recycling damaged organelles and proteins). Defects in lysosomal function are associated with a range of disorders, including lysosomal storage diseases, neurodegenerative disorders, and cancer.
