Golgi apparatus function

The Golgi apparatus functions as an organelle found within the cells of the majority of It is responsible for packaging proteins into “A living cell requires energy not only for all its functions, but also for the maintenance of its structure.”— Albert Szent-Gyorgyi Location And Structure The The location of the Golgi apparatus There are two different compartments within the Golgi body – the trans-Golgi network (TGN) and the cis-Golgi network (CGN). The CGN is the structure that takes in proteins and the TGN is the network that packages the proteins for transport to other areas of the cell, putting them into vesicles. The vesicles will then exit the TGN and move along through the cytoplasm of the cell to the cell surface, specialized secretory vesicles, or the lysosomes. The TGN is sometimes connected/adjacent to the rest of the stack, though it can also be separated from the stack. Endosomes are components of the endocytic Every cisternal stack has a cis-entry point and a trans-entry point. Every entry and exit point has its own unique biochemistry and morphology. Every unique stack also has its own enzymes that function to modify the protein cargo that moves through them. The compartmentalized nature of the Golgi body is useful for keeping enzymes separated, making sure that the proper enzymes only act on their respective targets, restricting processing to several different steps. The Golgi apparatus is usually larger and bigger in cells that create a substantial amount ...
