Function. The Golgi apparatus (salmon pink) in context of the secretory pathway. The Golgi apparatus is a major collection and dispatch station of protein products received from the endoplasmic reticulum (ER). Proteins synthesized in the ER are packaged into vesicles, which then fuse with the Golgi apparatus.
The Golgi apparatus, or Golgi complex, functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes, the plasma membrane, or secretion.
The amount of Golgi in different cell types again illustrates that form follows function within cells. Cells that engage in a great deal of secretory activity (such as cells of the salivary glands that secrete digestive enzymes or cells of the immune system that secrete antibodies) have an abundant number of Golgi.
Protein Composition of the Golgi Apparatus. The three primary functions of the Golgi apparatus are the transport, sorting and modification of both protein and lipid, and the protein composition of the organelle reflects these functions.
The Golgi apparatus is the central organelle mediating protein and lipid transport within the eukaryotic cell. Typically textbooks illustrate the Golgi as something resembling a stack of pita...
May 22, 2019 · The Golgi apparatus is a central intracellular membrane-bound organelle with key functions in trafficking, processing, and sorting of newly synthesized membrane and secretory proteins and lipids. To best perform these functions, Golgi membranes form a unique stacked structure.
Jul 19, 2023 · 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.
