Suppose that a transmembrane protein destined for the plasma membrane was labeled with a fluorescent dye on the part of the protein exposed on the outer face of the endoplasmic reticulum membrane. If the protein is distributed among cellular compartments, where would you expect the dye to be located?

The dye will be on the outer face of the endoplasmic reticulum, on the outer face of the Golgi apparatus, and on the intracellular face of the plasma membrane.

The dye will be on the outer face of the endoplasmic reticulum, on the inner face of the Golgi apparatus, and on the extracellular face of the plasma membrane.
