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.
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.
The word lysosome (/ ˈ l aɪ s oʊ s oʊ m /, / ˈ l aɪ z ə z oʊ m /) is Neo-Latin that uses the combining forms lyso-(referring to lysis and derived from the Latin lysis, meaning "to loosen", via Ancient Greek λύσις [lúsis]), and -some, from soma, "body", yielding "body that lyses" or "lytic body".
Organelles (literally "little organs") are usually membrane-bound structures inside the cell that have specific functions. Some major organelles that are suspended in the cytosol are the mitochondria, the endoplasmic reticulum, the Golgi apparatus, vacuoles, lysosomes, and in plant cells, chloroplasts.
Golgi apparatus (also called the Golgi body, Golgi complex, or dictyosome), an organelle in a eukaryotic cell; Golgi tendon organ, a proprioceptive sensory receptor organ; Golgi's method or Golgi stain, a nervous tissue staining technique; Golgi alpha-mannosidase II, an enzyme; Golgi cell, a type of interneuron found in the cerebellum
Receptors embedded in the membrane of the Golgi body bind specific cargo (such as dopamine) on the lumenal side of the vesicle. These cargo receptors then recruit a variety of proteins including other cargo receptors and coat proteins such as clathrin, COPI and COPII. As more and more of these coating proteins come together, they cause the ...
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).
The cis-Golgi network is involved in the phosphorylation of oligosaccharides on lysosomal proteins, a modification that helps target proteins to the lysosomes. The medial-Golgi is the site of important reactions like the trimming of mannose and the addition of GlcNAc, which is essential for the formation of complex glycan structures.
