Cells of the pancreas will incorporate radioactively labeled amino acids into proteins. This "tagging" of newly synthesized proteins enables a researcher to track the location of these proteins in a cell. In this case, we are tracking an enzyme that is eventually secreted by pancreatic cells. Which of the following is the most likely pathway for movement of this protein in the cell?

a. ER Golgi nucleus
b. Golgi ER lysosome
c. nucleus ER Golgi
d. ER Golgi vesicles that fuse with plasma membrane
e. ER lysosomes vesicles that fuse with plasma membrane


d. ER Golgi vesicles that fuse with plasma membrane
