Question

How do vesicles move inside of a cell?

Answer 1

Answer:

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

Explanation

Structurally. Cytoskeleton  forms the structural framework of the cytoplasm. It acts as  the skeletal framework  for reinforcement of   the cytoplasm for protection, intercellular motility, and migration.

Its 3 major structural and functional frameworks are  formed by actin filaments, intermediate filaments and microtubules.

Motor proteins are  molecular motors  essential for  muscle contraction,    movement, and transport of material in the cystosol. They obtained  energy through  hydrolyses of ATP to ADP for needed mechanical energy  of  motility.

Therefore  vesicles  are transported as  cytoskeleton motors across the cytosol using cytoskeleton as roadways and hydolysing ATP to generate mechanical energy for the mobility.

Answer 2

Answer:

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

Explanation:

These vesicles then catch a ride on a molecular motor such as kinesin or myosin, and travel along the cytoskeleton until they dock at the appropriate destination and fuse with the target membrane or organelle. In general, vesicles move from the ER to the cis Golgi, from the cis to the medial Golgi, from the medial to the trans Golgi, and from the trans Golgi to the plasma membrane or other compartments. Although most movement is in this direction, there are also vesicles that move back from the Golgi to the ER, carrying proteins that were supposed to stay in the ER (e.g. PDI) and were accidentally scooped up within a vesicle
