  2. Lysosome - Wikipedia

    en.wikipedia.org/wiki/Lysosome

    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.

  3. Organelle - Wikipedia

    en.wikipedia.org/wiki/Organelle

    The name organelle comes from the idea that these structures are parts of cells, as organs are to the body, hence organelle, the suffix -elle being a diminutive. Organelles are either separately enclosed within their own lipid bilayers (also called membrane-bounded organelles) or are spatially distinct functional units without a surrounding ...

  4. Endomembrane system - Wikipedia

    en.wikipedia.org/wiki/Endomembrane_system

    Lysosomes provide such an environment by maintaining a pH of 5.0 inside of the organelle. [37] If a lysosome were to rupture, the enzymes released would not be very active because of the cytosol's neutral pH. However, if numerous lysosomes leaked the cell could be destroyed from autodigestion.

  5. Food vacuole - Wikipedia

    en.wikipedia.org/wiki/Food_vacuole

    The food vacuole, or digestive vacuole, is an organelle found in simple eukaryotes such as protists.This organelle is essentially a lysosome.During the stage of the symbiont parasites' lifecycle where it resides within a human (or other mammalian) red blood cell, it is the site of haemoglobin digestion and the formation of the large haemozoin crystals that can be seen under a light microscope.

  6. Vacuole - Wikipedia

    en.wikipedia.org/wiki/Vacuole

    A vacuole (/ ˈ v æ k juː oʊ l /) is a membrane-bound organelle which is present in plant and fungal cells and some protist, animal, and bacterial cells. [ 1 ] [ 2 ] Vacuoles are essentially enclosed compartments which are filled with water containing inorganic and organic molecules including enzymes in solution , though in certain cases ...

  7. Endosome - Wikipedia

    en.wikipedia.org/wiki/Endosome

    The process of creating vesicles within the endosome is thought to be enhanced by the peculiar lipid BMP or LBPA, which is only found in late endosomes, endolysosomes or lysosomes. [12] When the endosome has matured into a late endosome/MVB and fuses with a lysosome, the vesicles in the lumen are delivered to the lysosome lumen.

  8. Cell (biology) - Wikipedia

    en.wikipedia.org/wiki/Cell_(biology)

    There are several types of organelles in a cell. Some (such as the nucleus and Golgi apparatus) are typically solitary, while others (such as mitochondria, chloroplasts, peroxisomes and lysosomes) can be numerous (hundreds to thousands). The cytosol is the gelatinous fluid that fills the cell and surrounds the organelles.

    en.wikipedia.org/wiki/Outline_of_cell_biology

    Lysosomes – It is a membrane-bound cell organelle found in most animal cells (they are absent in red blood cells). Structurally and chemically, they are spherical vesicles containing hydrolytic enzymes capable of breaking down virtually all kinds of biomolecules, including proteins, nucleic acids, carbohydrates, lipids, and cellular debris ...
