  2. Golgi apparatus - Wikipedia

    en.wikipedia.org/wiki/Golgi_apparatus

    The Golgi apparatus (/ ˈ ɡ ɒ l dʒ i /), also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells. [1] Part of the endomembrane system in the cytoplasm , it packages proteins into membrane-bound vesicles inside the cell before the vesicles are sent to their destination.

  3. Endomembrane system - Wikipedia

    en.wikipedia.org/wiki/Endomembrane_system

    The Golgi apparatus (also known as the Golgi body and the Golgi complex) is composed of separate sacs called cisternae. Its shape is similar to a stack of pancakes. The number of these stacks varies with the specific function of the cell. The Golgi apparatus is used by the cell for further protein modification.

  4. Organelle - Wikipedia

    en.wikipedia.org/wiki/Organelle

    Organelles are identified by microscopy, and can also be purified by cell fractionation. There are many types of organelles, particularly in eukaryotic cells. They include structures that make up the endomembrane system (such as the nuclear envelope, endoplasmic reticulum, and Golgi apparatus), and other structures such as mitochondria and ...

  5. Cisterna - Wikipedia

    en.wikipedia.org/wiki/Cisterna

    The trans-Golgi network is an important part of the Golgi. It is located on the trans face of the Golgi apparatus and is made up of cisternae. The cisternae play a crucial role in the packaging, modification, and transport functions for the cell overall.

  6. Cellular compartment - Wikipedia

    en.wikipedia.org/wiki/Cellular_compartment

    Both organelles, the mitochondria and chloroplasts (in photosynthetic organisms), are compartments that are believed to be of endosymbiotic origin. Other compartments such as peroxisomes, lysosomes, the endoplasmic reticulum, the cell nucleus or the Golgi apparatus are not of endosymbiotic origin.

  7. Endoplasmic reticulum - Wikipedia

    en.wikipedia.org/wiki/Endoplasmic_reticulum

    The transitional ER gets its name because it contains ER exit sites. These are areas where the transport vesicles which contain lipids and proteins made in the ER, detach from the ER and start moving to the Golgi apparatus. Specialized cells can have a lot of smooth endoplasmic reticulum and in these cells the smooth ER has many functions. [6]

  8. Microtubule organizing center - Wikipedia

    en.wikipedia.org/wiki/Microtubule_organizing_center

    The polarity of the microtubules is important for cellular transport, as the motor proteins kinesin and dynein typically move preferentially in the "plus" and "minus" directions respectively, along a microtubule, allowing vesicles to be directed to or from the endoplasmic reticulum and Golgi apparatus. Particularly for the Golgi apparatus ...

  9. Secretory protein - Wikipedia

    en.wikipedia.org/wiki/Secretory_protein

    In the Golgi apparatus, the sugar chains are modified by adding or removing certain sugars. The secretory protein leaves the Golgi apparatus by an uncoated vesicle. The secretory protein leaves the Golgi apparatus by an uncoated vesicle.
