Lysosome - Definition, Function & Structure - Biology Dictionary
2017年4月28日 · 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 - Wikipedia
Lysosomes are degradative organelles that act as the waste disposal system of the cell by digesting used materials in the cytoplasm, from both inside and outside the cell. Material from outside the cell is taken up through endocytosis , while material from the inside of the cell is digested through autophagy . [ 6 ]

3 天之前 · 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. If the cell is damaged beyond repair, lysosomes can help it to self-destruct in …
Lysosomes: Structure, Functions, Diagram - Microbe Notes
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.
Lysosome – Definition, Location, Structure, and Functions
2023年5月18日 · 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.
Lysosome: Definition, Structure & Function - Sciencing
2019年3月15日 · Lysosomes are small, membrane-bound sacks of acidic enzymes that digest cell waste. They maintain an interior acidity by using proton pumps from chemical reactions on their surface and in their interior. Lysosomes work by absorbing small pieces of cell debris and surrounding larger fragments.
Lysosomes - Definition, Structure, Formation, Functions, Types …
2024年4月6日 · Lysosomes form through the union of vesicles in the Golgi complex and endosomes. Endosomes are vesicles created by endocytosis when an area of plasma membrane gets cut off and is then internalized by cells.
