  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

    Bar, 500 nm. 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 ...

  4. Endomembrane system - Wikipedia

    en.wikipedia.org/wiki/Endomembrane_system

    The endomembrane system is composed of the different membranes (endomembranes) that are suspended in the cytoplasm within a eukaryotic cell. These membranes divide the cell into functional and structural compartments, or organelles. In eukaryotes the organelles of the endomembrane system include: the nuclear membrane, the endoplasmic reticulum ...

  5. Endoplasmic reticulum - Wikipedia

    en.wikipedia.org/wiki/Endoplasmic_reticulum

    Dark small circles in the network are mitochondria. The endoplasmic reticulum (ER) is a part of a transportation system of the eukaryotic cell, and has many other important functions such as protein folding. It is a type of organelle made up of two subunits – rough endoplasmic reticulum (RER), and smooth endoplasmic reticulum (SER).

  6. Vesicle (biology and chemistry) - Wikipedia

    en.wikipedia.org/wiki/Vesicle_(biology_and...

    Vesicle (biology and chemistry) Scheme of a liposome formed by phospholipids in an aqueous solution. In cell biology, a vesicle is a structure within or outside a cell, consisting of liquid or cytoplasm enclosed by a lipid bilayer. Vesicles form naturally during the processes of secretion (exocytosis), uptake (endocytosis), and the transport of ...

  7. Lysozyme - Wikipedia

    en.wikipedia.org/wiki/Lysozyme

    Lysozyme (EC 3.2.1.17, muramidase, N-acetylmuramide glycanhydrolase; systematic name peptidoglycan N-acetylmuramoylhydrolase) is an antimicrobial enzyme produced by animals that forms part of the innate immune system. It is a glycoside hydrolase that catalyzes the following process: Hydrolysis of (1→4)-β-linkages between N -acetylmuramic ...

  8. Plasma cell - Wikipedia

    en.wikipedia.org/wiki/Plasma_cell

    Plasma cells, also called plasma B cells or effector B cells, are white blood cells that originate in the lymphoid organs as B cells [1][2] and secrete large quantities of proteins called antibodies in response to being presented specific substances called antigens.

  9. Lysosomal lipase - Wikipedia

    en.wikipedia.org/wiki/Lysosomal_lipase

    The primary function of lysosomal lipase is to hydrolyze lipids such as triglycerides and cholesterol. [1] These fats are transported and degraded into free fatty acids. Lysosomal lipases function optimally at an acidic pH which are complementary with the environment found in the lysosomal lumen. [2] These enzymes were believed to only ...
