Question

If you could follow a small region of a membrane as it follows from organelle to organelle, which of the following sequences would you observe?

• A. Golgi apparatus $\to$ lysosome $\to$ ER
• B. Nuclear envelope $\to$ lysosome $\to$ Golgi apparatus.
• C. ER $\to$Golgi apparatus $\to$plasma membrane
• D. ER $\to$chloroplast $\to$mitochondrion

Answer 1

The correct option is C ER $\to$Golgi apparatus $\to$plasma membrane

If we could follow a small region of a membrane as it follows from organelle to organelle, it will go from ER to Golgi apparatus and then it would flow to the plasma membrane following the Golgi apparatus. This forms the endomembrane system of the eukaryotic cell.

Hence, the correct answer is 'ER $\to$Golgi apparatus $\to$plasma membrane'.
