How do the Golgi apparatus and vesicles interact in an animal cell?
a
The Golgi apparatus degrades proteins, and the vesicles synthesize replacement proteins in the cell.
b
The Golgi apparatus transports proteins, and the vesicles control the transportation of the proteins in the cell.
c
The Golgi apparatus packages proteins, and the vesicles transport the packages to various locations in the cell.
d
The Golgi apparatus synthesizes proteins, and the vesicles package the proteins for transport in the cell.
c
The Golgi apparatus packages proteins, and the vesicles transport the packages to various locations in the cell.
c
The Golgi apparatus packages proteins, and the vesicles transport the packages to various locations in the cell.
The correct answer is c) The Golgi apparatus packages proteins, and the vesicles transport the packages to various locations in the cell.
The Golgi apparatus and vesicles work together in the process of protein transport and packaging within an animal cell. Here's how they interact:
1. Protein Production: Proteins are synthesized in the endoplasmic reticulum (ER) of a cell.
2. Golgi Apparatus: Once synthesized, the proteins are transported from the ER to the Golgi apparatus. The Golgi apparatus is a stack of membrane-bound compartments known as cisternae.
3. Protein Modification: In the Golgi apparatus, the proteins undergo further processing and modifications. This may include the addition of sugars (glycosylation) or the removal of certain amino acids.
4. Packaging: The Golgi apparatus also plays a crucial role in packaging the proteins into transport vesicles. These vesicles bud off from the Golgi apparatus, enclosing the proteins within their membranes.
5. Vesicle Formation: The vesicles containing the packaged proteins are formed through the budding process. These vesicles are small, membrane-bound sacs that transport various molecules within the cell.
6. Vesicle Transport: The vesicles then move towards their destination within the cell. They can target specific locations, such as other organelles or the cell membrane.
7. Vesicle Fusion: Upon reaching their destination, the vesicles fuse with the target membrane, releasing the packaged proteins into the desired location. This allows the proteins to fulfill their specific functions within the cell.
So, in summary, the Golgi apparatus packages proteins into transport vesicles, and the vesicles transport these packages to various locations within the cell for further processing or use.
