Main function of Golgi bodies in …

The golgi apparatus is a membrane bound organelle found in most cells. It  is responsible for packaging proteins into vesicles prior to secretion and therefore plays a key role in the secretory pathway. In this article we shall look at the structure and function of the golgi apparatus and its role in Wilson’s disease. Structure The golgi is made of 5-8 folds called cisternae. The cisternae contain specific enzymes creating five functional regions which modify proteins passing through them in a stereotypical way, as follows: Cis-Golgi network: faces the nucleus, forms a connection with the endoplasmic reticulum and is the entry point into the Golgi apparatus. Cis-Golgi: major processing area allowing biochemical modifications. Medial-Golgi: major processing area allowing biochemical modifications. Trans-Golgi: major processing area allowing biochemical modifications. Trans-Golgi network: exit point for vesicles budding off the Golgi surface, packages and sorts biochemicals into the vesicles according to their destination.

The golgi apparatus is a membrane bound organelle found in most cells. It is responsible for packaging proteins into vesicles prior to secretion and therefore plays a key role in the secretory pathway.

Its main function is the packaging and secretion of proteins. It receives proteins from Endoplasmic Reticulum. It packages it into membrane-bound vesicles, which are then transported to various destinations, such as lysosomes, plasma membrane or secretion. They also take part in the transport of lipids and the formation of lysosomes.

Post-translational modification and enzymatic processing occur near the membrane surface in Golgi bodies, e.g. phosphorylation, glycosylation, etc.

Golgi apparatus is the site for the synthesis of various glycolipids, sphingomyelin, etc.

In the plant cells, complex polysaccharides of the cell wall are synthesised in the Golgi apparatus.
