Components of the Endomembrane System: The Golgi Apparatus
- It is a stack of membranous bodies called cisternae. It was discovered by Camillo Golgi, an Italian physicist, in 1897.
- These are present in both plant cells and animal cells. In-plant cells, they occur as unconnected units called dictyosomes.
- Like the endoplasmic reticulum, they are also made up of tubules and vesicles apart from cisternae.
- The face of the Golgi apparatus that receives vesicles from the ER is called a cis face.
- The opposite of cis face is the trans face which gives off vesicles for the destination.
- The Golgi apparatus is primarily involved in the processing of proteins generated in the endoplasmic reticulum.
- It is also responsible for their transport to the different parts of the cell.
- The Golgi apparatus functions as a platform for the process of addition of sulfate groups into protein molecules, glycosylation and phosphorylation.
