Which Structure is the Site of the Synthesis of Proteins

Question

Which structure is the site of the synthesis of proteins that may be exported from the cell?
A)rough ER
B)lysosomes
C)plasmodesmata
D)Golgi vesicles
E)free cytoplasmic ribosomes

Accepted Answer

Rough ER is the site of protein synthesis that may be exported from the cell. The ribosomes attached to the rough ER synthesize proteins and the ER modifies and folds them before they are transported to the Golgi apparatus for further processing and eventual secretion out of the cell.
