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
A lysosome (/ ˈ l aɪ s ə ˌ s oʊ m /) 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.

2024年8月23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.
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.
