  2. Lysosome - Wikipedia

    en.wikipedia.org/wiki/Lysosome

    Lysosome. Centrosome. Cell membrane. 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.

  3. Endosome - Wikipedia

    en.wikipedia.org/wiki/Endosome

    Endosomes are a collection of intracellular sorting organelles in eukaryotic cells. They are parts of the endocytic membrane transport pathway originating from the trans Golgi network. Molecules or ligands internalized from the plasma membrane can follow this pathway all the way to lysosomes for degradation or can be recycled back to the cell ...

  4. Numeric precision in Microsoft Excel - Wikipedia

    en.wikipedia.org/wiki/Numeric_precision_in...

    Numeric precision in Microsoft Excel. As with other spreadsheets, Microsoft Excel works only to limited accuracy because it retains only a certain number of figures to describe numbers (it has limited precision). With some exceptions regarding erroneous values, infinities, and denormalized numbers, Excel calculates in double-precision floating ...

    en.wikipedia.org/wiki/Microsoft_Excel

    Microsoft Excel is a spreadsheet editor developed by Microsoft for Windows, macOS, Android, iOS and iPadOS. It features calculation or computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA). Excel forms part of the Microsoft 365 suite of software.

  6. Cytosis - Wikipedia

    en.wikipedia.org/wiki/Cytosis

    Endocytosis: The membrane of the cell invaginates, creating a small circular pit that is taken into the cytosol of the cell. This circular membrane coated pit is a vesicle that is transported to the lysosome of the cell to be degraded by enzymes. -Cytosis is a suffix that either refers to certain aspects of cells ie cellular process or ...

  7. Autophagosome - Wikipedia

    en.wikipedia.org/wiki/Autophagosome

    Autophagosome. The autophagic process is divided into five distinct stages: Initiation, phagophore nucleation, autophagosomal formation (elongation), autophagosome-lysosome fusion (autophagolysosome) and cargo degradation. [1] An autophagosome is a spherical structure with double layer membranes. [2] It is the key structure in macroautophagy ...

  8. Proteasome - Wikipedia

    en.wikipedia.org/wiki/Proteasome

    Enzymes that help such reactions are called proteases. Proteasomes are part of a major mechanism by which cells regulate the concentration of particular proteins and degrade misfolded proteins. Proteins are tagged for degradation with a small protein called ubiquitin. The tagging reaction is catalyzed by enzymes called ubiquitin ligases.

  9. TMEM106B - Wikipedia

    en.wikipedia.org/wiki/TMEM106B

    Transmembrane protein 106B is a protein that is encoded by the TMEM106B gene. [5] It is found primarily within neurons and oligodendrocytes in the central nervous system with its subcellular location being in lysosomal membranes. TMEM106B helps facilitate important functions for maintaining a healthy lysosome, and therefore certain mutations ...
