You are tracing the path of secretory protein from its synthesis to its export from a cell. You have added radioactive amino acids to a culture of cells, and then measured the amount of radioactivity that shows up in the proteins of each of the following fractions at different times after the addition. List the order in which the proteins of these fractions first exhibit radioactivity. I â secretory vesicles
II â rough ER
III â smooth ER
IV â Golgi
V â nucleus

a. III â II â I â out of the cell
b. IIIâ II â IV â V âout of the cell
c. V â III âII â I â out of the cell
d. IVâ III â II â I â out of the cell
e. II â III â IV â I â out of the cell
