  2. Endocytosis - Wikipedia

    en.wikipedia.org/wiki/Endocytosis

    Endocytosis is a cellular process in which substances are brought into the cell. The material to be internalized is surrounded by an area of cell membrane, which then buds off inside the cell to form a vesicle containing the ingested materials. Endocytosis includes pinocytosis (cell drinking) and phagocytosis (cell eating). It is a form of ...

    en.wikipedia.org/wiki/File:Endocytosis_types.svg

    Endocytosis (IPA: [ɛndəʊsaɪˈtəʊsɪs]) is a process whereby cells absorb material (molecules such as proteins) from the outside by engulfing it with their cell membrane. It is used by all cells of the body because most substances important to them are polar and consist of big molecules, and thus cannot pass through the hydrophobic plasma ...

    English: Endocytosis. For example, coronavirus binds to the ACE2 receptor of the epithelial cell. ... This image was uploaded as part of Russian Science Photo ...

  5. Receptor-mediated endocytosis - Wikipedia

    en.wikipedia.org/wiki/Receptor-mediated_endocytosis

    Receptor-mediated endocytosis (RME), also called clathrin-mediated endocytosis, is a process by which cells absorb metabolites, hormones, proteins – and in some cases viruses – by the inward budding of the plasma membrane (invagination).

  6. Viral entry - Wikipedia

    en.wikipedia.org/wiki/Viral_entry

    Viral entry via endocytosis. Viruses with no viral envelope enter the cell generally through endocytosis; they “trick” the host cell to ingest the virions through the cell membrane. Cells can take in resources from the environment outside of the cell, and these mechanisms may be exploited by viruses to enter a cell in the same manner as ...

  7. Endomembrane system - Wikipedia

    en.wikipedia.org/wiki/Endomembrane_system

    Endocytosis refers to when substances are taken into the cell, whereas for exocytosis substances are moved from the cell into the extracellular space. Material to be taken-in is surrounded by the plasma membrane, and then transferred to a vacuole. There are two types of endocytosis, phagocytosis (cell eating) and pinocytosis (cell drinking). In ...

  8. Cytosis - Wikipedia

    en.wikipedia.org/wiki/Cytosis

    Mechanism of clathrin-dependent endocytosis. Clathrin-coated pits in endocytosis: The membrane of the cell invaginates using the protein clathrin. The clathrin uses actin to pull together the sides of the plasma membrane and form a vesicle inside the cellular cytosol. Receptor-mediated endocytosis Receptor-mediated endocytosis is a mode of ...

  9. Pinocytosis - Wikipedia

    en.wikipedia.org/wiki/Pinocytosis

    Pinocytosis. In cellular biology, pinocytosis, otherwise known as fluid endocytosis and bulk-phase pinocytosis, is a mode of endocytosis in which small molecules dissolved in extracellular fluid are brought into the cell through an invagination of the cell membrane, resulting in their containment within a small vesicle inside the cell.
