Golgi apparatus

The Golgi apparatus is the only organelle named after a scientist, Camillo Golgi.The Golgi is found in both animal and plant eukaryotic cells and is located close to the endoplasmic reticulum. The Golgi apparatus is abundant in cells that specialize in secretion.

The Golgi apparatus consists of a series of flattened membrane sacs, known as cisternae.Enzymes within the cisternae are able to modify the proteins by addition of carbohydrates (glycosylation) and phosphates (phosphorylation).One end of the Golgi apparatus, the cis-Golgi network, serves as a receiving point for macromolecules.As the products move through the Golgi apparatus, they are sorted and modified. The Golgi apparatus also manufactures macromolecules and lysosomes. The trans-Golgi network near the plasma membrane utilizes vesicles to transport the products to other locations in the cell or to the plasma membrane for secretion.

The Golgi apparatus is known as the cell’s post office. It processes and modifies proteins and lipids and then sorts and labels them for distribution. The most important duty of the Golgi apparatus is to sort the wide variety of macromolecules produced by the cell and target them for distribution to their proper location. If the cell did not have the Golgi apparatus, proteins would not be modified and transported. The cell would not function correctly, and the cell could malfunction or die.
