Question
In order for a protein, such as collagen, to be secreted, it will at some point have to bind to a protein transporter at the plasma membrane. move from the Golgi complex to the ER. go through the process of endocytosis. be carried in a vesicle from the ER to the Golgi complex.
Solution
The correct answer is: "be carried in a vesicle from the ER to the Golgi complex."
Here's the step-by-step process:
-
Protein synthesis begins in the ribosomes, which are either free-floating in the cytoplasm or attached to the endoplasmic reticulum (ER). In the case of collagen, the ribosomes are attached to the ER.
-
Once the protein is synthesized, it is transported into the lumen of the ER, where it undergoes folding and post-translational modifications.
-
The protein is then packaged into a transport vesicle, a small, membrane-bound structure.
-
This vesicle buds off from the ER and is transported to the Golgi complex.
-
In the Golgi complex, the protein undergoes further modifications and is sorted for transport to its final destination.
-
The protein is then packaged into a secretory vesicle, which buds off from the Golgi complex.
-
This vesicle moves to the plasma membrane, where it fuses with the membrane and releases the protein outside the cell. This process
