The correct sequence of organelles that a protein would take if it were being exported from the cell is:
Ribosome -> Rough ER -> Vesicle -> Golgi Apparatus -> Vesicle -> Cell Membrane
To determine the correct answer, let's analyze each option and see which one follows the correct order:
Option 1: Ribosome -> Vesicle -> Rough ER -> Vesicle -> Golgi Apparatus -> Cell Membrane
This option starts with the ribosome, which is where protein synthesis begins. After the ribosome, the protein would be transported to the rough ER for further processing. From the rough ER, it would be packaged into a vesicle and then transported to the Golgi apparatus for further modification. Finally, it would be packaged into another vesicle and transported to the cell membrane for export. This option is incorrect because it skips the rough ER before reaching the vesicle after Golgi apparatus.
Option 2: Ribosome -> Rough ER -> Vesicle -> Golgi Apparatus -> Vesicle -> Cell Membrane
This option follows the correct sequence. It starts with the ribosome, followed by the rough ER, where the protein undergoes further processing. The protein is then packaged into a vesicle and transported to the Golgi apparatus, where it undergoes further modification. From there, it is packaged into another vesicle and transported to the cell membrane for export. This is the correct answer.
Option 3: Smooth ER -> Vesicle -> Golgi apparatus -> Rough ER -> Vesicle -> Nucleus
This option is incorrect because it starts with the smooth ER, which is not part of the pathway for protein export.
Option 4: Ribosome -> Smooth ER -> Vesicle -> Cell Membrane -> Vesicle -> Rough ER
This option is incorrect because it starts with the smooth ER, which is not the initial organelle involved in protein synthesis. Additionally, the sequence of vesicle -> cell membrane -> vesicle -> rough ER is not correct.
Therefore, the correct answer is:
Ribosome -> Rough ER -> Vesicle -> Golgi Apparatus -> Vesicle -> Cell Membrane
