Correct Question:
Anterograde movement of transition vesicles is from __________.
A. the rough ER to the trans Golgi.
B. the trans Golgi to secrete at the plasma membrane.
C. the rough ER to the cis Golgi.
D. the cis Golgi to the trans Golgi.
Answer:
C. the rough ER to the cis Golgi
Explanation:
Vesicles are small enclosed sacs located inside or outside a cell. They are formed whenever there is a need for secretion of substances or transportation of materials from one organelle to another organelle within cell. Vesicles can also be used to store nutrients or water in the cell.
We have 3 classes of vesicles and they are:
a. Lysosomes
b. Transition or transport vesicles
c. Vacuoles.
The anterograde movement of transition vesicles is from the rough Endoplasmic Reticulum to the cis Golgi apparatus.
This movement takes place when proteins are made in the ribosomes found in the Endoplasmic Reticulum. The transition vesicles now transport this proteins from the rough Endoplasmic Reticulum to the cis Golgi apparatus where they get matured before they are released into the cytoplasm.
