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.
Lysosomes are membrane-bound organelles and the area within the membrane is called the lumen, which contains the hydrolytic enzymes and other cellular debris. The diagram below shows the lysosome structure within a cell. Lysosome diagram showcasing enzyme complexes within the single-walled membrane.

Apr 13, 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.

A lysosome (/ ˈ l aɪ s ə ˌ s oʊ m /) is a single membrane-bound organelle found in many animal cells. 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.
May 18, 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.
Mar 15, 2019 · Lysosomes are small cell organelles in nucleus-bearing or eukaryotic cells. They are located in the cytosol of the cells, floating freely within the cells outside the nucleus. They have a simple structure made up of an outer lysosomal membrane surrounding an acidic interior fluid.
Jul 19, 2023 · Structure. Lysosomes are acidic membrane-bound organelles found within cells, usually around 1 micrometre in length. Lysosomes contain numerous hydrolytic enzymes which catalyse hydrolysis reactions. The membrane surrounding the lysosome is vital to ensure these enzymes do not leak out into the cytoplasm and damage the cell from within.
