plasma membrane). How would the protein be oriented in the ER and vesicle
membranes before reaching the plasma membrane?
A. facing the inside of the ER lumen but the outside the transport vesicle membrane
B. facing the inside of the ER lumen and the inside the transport vesicle membrane
C. attached outside the ER and outside the transport vesicle
D. attached outside the ER but facing the inside of the transport vesicle
E. completely embedded in the hydrophobic center of both the ER
