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.
28 kwi 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.
30 paź 2024 · lysosome, subcellular organelle that is found in nearly all types of eukaryotic cells (cells with a clearly defined nucleus) and that is responsible for the digestion of macromolecules, old cell parts, and microorganisms.
18 maj 2023 · Lysosomes are membrane-bound cell vesicles found in the cytoplasm of all animal cells. They were discovered and named by Christian de Duve in 1955. de Duve used lysosomes to describe an organelle containing hydrolytic enzymes capable of breaking down biological polymers such as nucleic acid, proteins, carbohydrates, and lipids.
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.
2 sty 2019 · In this Review, Lawrence and Zoncu discuss the central role of the lysosome in cellular metabolism, including in macromolecular catabolism and nutrient recycling, and organelle crosstalk.
20 kwi 2015 · Lysosomes are membrane-bound organelles that are found in animal cells and contain over 50 different acid hydrolases. These dynamic organelles function at the end of the endocytic, autophagic and phagocytic pathways, with lysosomal acid hydrolases being used to break down a wide variety of macromolecules delivered through these pathways.
