Which structure is the site of the synthesis of proteins that may be exported from the cell?
1 plasmodesmata
2 tight junctions
3 lysosomes
4 rough er
5 golgi vesicles
i just wanted to check my answer, i think it is 5, bec of the "export" and proteins are slightly modified at the golgi too

Answer is 4: rough e.r.
More specifically, these proteins are made on the ribosomes that are stuck on the rough e.r.
The Golgi apparatus does not synthesize or make proteins. It does process, sort, and package proteins that will be exported. The Golgi apparatus gets these proteins from the rough e.r. which got them from the ribosomes on the e.r. surface.
Your teacher wants you to know that the ribosomes on the rough e.r. makes proteins that will be exported. The ribosomes that are loose or free in the cytoplasm and not stuck on the e.r. are more likely to make proteins that will be used inside the cell and not exported.

i believe it is the golgi vesicles.
not #1, not #2, lysosomes .... no
ok, golgi vesicles

I think you are right.
I defer to ecolink on this problem. You need to also.
