Lysosome - Wikipedia
A lysosome (/ ˈlaɪsəˌsoʊm /) is a single membrane-bound organelle found in many animal cells. [1][2] They are spherical vesicles that contain hydrolytic enzymes that digest many kinds of biomolecules. A lysosome has a specific composition, of both its membrane proteins and its lumenal proteins.
Lysosomes - The Cell - NCBI Bookshelf - National Center for ...
Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers—proteins, nucleic acids, carbohydrates, and lipids. Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of ...
Lysosome - Definition, Function & Structure - Biology Dictionary
Apr 28, 2017 · Lysosomes are specialized vesicles within cells that digest large molecules through the use of hydrolytic enzymes. Vesicles are small spheres of fluid surrounded by a lipid bilayer membrane, and they have roles in transporting molecules within the cell.
Lysosome | Description, Formation, & Function | Britannica
Oct 30, 2024 · Lysosomes contain a wide variety of hydrolytic enzymes (acid hydrolases) that break down macromolecules such as nucleic acids, proteins, and polysaccharides. These enzymes are active only in the lysosome’s acidic interior; their acid-dependent activity protects the cell from self-degradation in case of lysosomal leakage or rupture, since the ...
