Question

proteins and lipids leave the endomembrane system (the golgi, specifically) in special transport vesicles that carry them to their final destination. how do transport vesicles carry out this function? select all that apply.
vesicles are carried by microtubule motor proteins such as kinesin.
ribosomes help vesicles bring proteins to their final destination within the cell.
the signal sequence directs vesicles to carry proteins to their final destination in the cell.
the vesicle membrane \zip code\ proteins help direct the vesicle to the final membrane destination.

Explanation:

• Vesicles are transported along microtubules by motor - proteins like kinesin.
• Signal sequences on proteins guide vesicles to the correct destination within the cell.
• Vesicle - membrane "zip - code" proteins help in targeting the vesicle to the appropriate membrane. Ribosomes are involved in protein synthesis, not in vesicle - mediated transport of proteins to their final destination.

Answer:

• Vesicles are carried by microtubule motor proteins such as kinesin.
• The signal sequence directs vesicles to carry proteins to their final destination in the cell.
• The vesicle membrane "zip code" proteins help direct the vesicle to the final membrane destination.
