A certain type of cell makes antibodies that are secreted from the cell. It is possible to track the path of these as they leave the cell by labeling them with radioactive isotopes. Which of the following might be the path of antibodies from where they are made to the cell membrane?
A. Golgi complex to lysosomes to cell membrane
B. rough endoplasmic reticulum to Golgi complex to cell membrane
C. nucleus to Golgi complex to cell membrane
D. smooth endoplasmic reticulum to lysosomes to cell membrane
Choose A, B, C or D as your solution.
The correct answer is B. Antibodies are proteins that are secreted from the cell. Proteins would be produced and labeled by the rough endoplasmic reticulum. From there, they would be sorted by the Golgi complex and finally directed to the cell membrane for secretion.
