How do vesicles move inside of a cell?
lana [763]

Answer:

C. They are carried by motor proteins using the cytoskeleton as a "roadway"

Explanation:

Vesicles hitch a ride on molecular motors such as kinesin or myosin, moving along the cytoskeleton until they reach their intended location, where they then fuse with the target membrane or organelle. Typically, vesicles progress from the ER to the cis Golgi, followed by movement from the cis to the medial Golgi, from the medial to the trans Golgi, and finally from the trans Golgi to the plasma membrane or other cellular compartments. While the predominant direction is forward, there are also vesicles that return from the Golgi to the ER, carrying proteins that should have remained in the ER (e.g., PDI) that were inadvertently enclosed in a vesicle.
