What Is the Golgi Apparatus?

The Golgi apparatus is composed of flat capsules composed of unit membranes stacked together. The flat sac is round, with enlarged edges and perforations. All Golgi apparatus in a cell are collectively called Golgi apparatus. A Golgi body usually has 5-8 sacs with liquid contents. ^[1]

The main functions of the Golgi apparatus will be

1. Cis Golgi receives newly synthesized substances from the endoplasmic reticulum and classifies them into the Golgi intermediate membrane sac. Most of the proteins and lipids return to the endoplasmic reticulum (resident in the endoplasm Online). Others include: O-linking of proteins, acylation of transmembrane proteins, and assembly of coronaviruses.

2. Medial Golgi has most glycosylation modification, glycolipid formation, and polysaccharide formation. Has a large membrane surface, increasing the effective area for synthesis and modification.

3, trans Golgi pH is lower than other parts. The function is the classification and packaging and export of proteins, "late" protein modification. And guarantee protein and lipid

1. Golgi body hypertrophy. Golgi hypertrophy is seen when cell secretions and enzyme production are vigorous. When macrophages are active in phagocytosis, many phagosomes, Golgi complexes are formed, and many Golgi vesicles are broken from them.

2. Golgi atrophy. The Golgi body became smaller and partially disappeared when various cells atrophied.

3. Golgi injury. Dilatation of the flat sacs and disintegration of the flat sacs, macrovesicles, and vesicles mostly occur.
