Proteins are synthesized by ribosomes in two main locations inside the cell: in the endoplasmic reticulum and in the cytosol. After synthesis, proteins may or may not be brought to the Golgi bodies for further processing, depending on the site of its function.
Choose which protein/(s) in the list below are synthesized by ribosomes attached to the ER.
A. A protein that resides in the chloroplast
B. A protein that will be secreted into the extracellular space
C. A nuclear protein
D. A membrane protein that shuttles between the plasma membrane and an endosome
E. A protein that resides between the inner and outer nuclear membranes
