Golgi Apparatus Flashcards
Where is the Golgi apparatus located in a cell?
Found in the cytoplasm, near the endoplasmic reticulum and the nucleus.
What is the structure of the Golgi apparatus?
It is made up of flattened, stacked pouches called cisternae.
What is the cis region of the Golgi apparatus?
The region that receives vesicles from the endoplasmic reticulum.
What is the trans region of the Golgi apparatus?
The region where vesicles bud off and travel to specific destinations (e.g., the cell membrane or lysosome).
What is the medial region of the Golgi apparatus?
The region located between the cis and trans regions.
What surrounds the Golgi apparatus?
Numerous vesicles that transport proteins and lipids to specific destinations within or outside the cell.
What role do enzymes in the Golgi apparatus play?
They facilitate the modification of proteins and lipids as they pass through the different cisternae.
What is the primary function of the Golgi apparatus?
To modify proteins and lipids produced by the endoplasmic reticulum.
What are some specific modifications performed by the Golgi apparatus?
Division of oligosaccharides, addition of fatty acids or phosphate groups, or removal of monosaccharides.
What is the Golgi apparatus’ role in sorting?
It directs proteins and lipids to their final destinations within or outside the cell.
What is a major site of carbohydrate addition in the cell?
The Golgi apparatus, where carbohydrates are added to proteins and lipids.
What does the Golgi produce?
Lysosomes and other specialized vesicles.
What are the three main regions of the Golgi complex?
The cis region, the trans region and the medial region
What is cisternae?
The flattened membrane vesicle found in both the Golgi apparatus and the ER
