You Have Genetically Engineered a Yeast Cell to Make a Protein

You have genetically engineered a yeast cell to make a protein that will ultimately be secreted from the cell. If all is functioning well,in which order (from first to last) do you expect to find the protein in the cell until it is secreted?

A) rER → Golgi → secretory vesicle → environment
B) rER → Golgi → sER → nucleus → environment
C) nucleus → rER → Golgi → secretory vesicle → environment
D) sER → Golgi → secretory vesicle → environment
E) rER → secretory vesicle → Golgi → environment
