A collection of small flat sacs formed by membranes within the cytoplasm of a cell (gel-like fluid). The Golgi body is responsible for preparing proteins and lipid (fat) molecules for use in other parts of the cell and outside of the cell. A cell organelle is the Golgi body. Also known as the Golgi apparatus and the Golgi complex.
A cell’s constituents. A cell is encased in a membrane with receptors on its surface. The nucleus, mitochondria, endoplasmic reticulum, and Golgi complex are all small structures found inside a cell. Each of these serves a specific purpose in the cell.
Transport from the ER through the Golgi Apparatus
Newly synthesised proteins enter the biosynthetic-secretory pathway in the ER by crossing the ER membrane from the cytosol. These proteins are successively modified as they travel from the ER to the Golgi apparatus, and then from the Golgi apparatus to the cell surface and elsewhere. Transferring from one compartment to the next necessitates a careful balance of forward and backward (retrieval) transport pathways. Some transport vesicles select cargo molecules and transport them to the next compartment in the pathway, whereas others retrieve escaped proteins and return them to a previous compartment where they normally function.
As a result, the pathway from the ER to the cell surface involves numerous sorting steps that constantly select membrane and soluble lumenal proteins for packaging and transport—in vesicles or organelle fragments that bud for the ER and Golgi apparatus.
Function of Golgi body
The golgi apparatus alters proteins and lipids from the endoplasmic reticulum. These biochemicals are exocytosed from the golgi before being delivered to various intracellular or extracellular targets.
Protein processing is the addition, removal, or modification of carbohydrates in glycoprotein carbohydrate regions.
Lipid processing – the addition of phosphate groups and glycoproteins to endoplasmic reticulum lipids (such as cholesterol) to produce the phospholipids that make up the cell membrane.
Golgi Apparatus
The Golgi apparatus is made up of flattened fluid-filled sacs that regulate molecule flow in a cell. This is also true for protein. To complete the protein’s production, carbohydrates are added.
This finished product, glycoprotein, is ‘plucked off’ the Golgi apparatus and transported by a cell membrane vesicle. When this vesicle reaches the cell membrane, it binds to a surface receptor and excretes the protein, allowing it to perform its function.
These newly formed glycoproteins (proteins with added carbohydrates) are used in a variety of ways, resulting in a wide variety of proteins based on their function. This is looked into in the

Distinguishing Features of Golgi
A Golgi apparatus is made up of flat sacs called cisternae. The sacs are stacked in a semicircular, bent shape. Each stacked grouping has a membrane that separates its interior from the cytoplasm of the cell. Protein interactions in the Golgi membrane are responsible for their distinct shape. The force that shapes this organelle is generated by these interactions.
The Golgi apparatus has a high degree of polarity. The composition and thickness of membranes at one end of the stack differ from those at the other. The “receiving” department is on one end (cis face), while the “shipping” department is on the other (trans face). The ER is closely associated with the cis face.
Golgi Body Function
Organelle function is heavily reliant on its structure. However, the reason why Golgi stack formation is important for its function has largely remained a mystery in the field for many decades.
In budding yeast (Saccharomyces cerevisiae), golgi cisternae do not normally form stacks, implying that stacking is not absolutely necessary for cell survival.
Golgi stacking, on the other hand, is a prominent feature in all metazoans and many unicellular eukaryotes, implying that it has important functional implications. For starters, stacking may have an effect on protein trafficking. Stacking should improve protein trafficking because the close spatial arrangement of cisternae reduces the distance that molecules must travel; local tethering proteins facilitate vesicle fusion with Golgi membranes (Lupashin and Sztul, 2005). Stacking, on the other hand, limits the surface.
