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.

2017年4月28日 · Lysosome Definition 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 …

2025年1月22日 · 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.

2 天之前 · A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.

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.

Organization of the lysosome. Lysosomes contain a variety of acid hydrolases that are active at the acidic pH maintained within the lysosome, but not at the neutral pH of the cytosol.

2019年3月15日 · Lysosomes are round membrane-bound organelles with a single outer lysosomal membrane. The membrane is impervious to the acidic contents of the lysosome. This protects the rest of the cell from the digestive enzymes inside the membrane. Once the acidic pH is established, the lysosome can digest cell waste products, old cell parts and other debris.

2024年4月6日 · Definition of Lysosome Lysosomes are membrane-bound organelles in animal cells containing hydrolytic enzymes that digest cellular waste, debris, and foreign substances, facilitating intracellular and occasional extracellular degradation.

2024年4月6日 · What are Lysosomes? Lysosomes are membrane-boundand dense granular structures that contain hydrolytic enzymes that are responsible for digestion in extracellular and intracellular cells. The term “lysosome” is composed of two words “lysis” which means breakdown, and “soma” which means body.

2023年11月11日 · Lysosomes are membrane-bound, dense granular structures containing hydrolytic enzymes responsible mainly for intracellular and extracellular digestion. The word “lysosome” is made up of two words “lysis” meaning breakdown and “soma” meaning body.
