You study a transmembrane protein that is trafficked through theendoplasmic reticulum but ultimately Γ’ΒΒlivesΓ’ΒΒ in the plasmamembrane. Suppose the domain of this protein which is exposed onthe outer face of the endoplasmic reticulum membrane was covalently(and specifically) labeled with a fluorescent dye in a living cell.When the protein is distributed among cellular compartments, wherewould you expect the dye to be located?
Question 7 options:
A) The dye will be on the outer face of the endoplasmicreticulum, on the inner face of the Golgi apparatus, and on theextracellular face of the plasma membrane.
B) The dye will be on the inner face of the endoplasmicreticulum, on the inner face of the Golgi apparatus, and on theintracellular face of the plasma membrane.
C) The dye will be on the outer face of the endoplasmicreticulum, on the outer face of the Golgi apparatus, and on theintracellular face of the plasma membrane.
D) The dye will be on the outer face of the endoplasmicreticulum, on the outer face of the Golgi apparatus, and on theextracellular face of the plasma membrane.
