What is the correct sequence of organelles involved in the synthesis, processing, and secretion of a protein that is destined for the plasma membrane?

  • A: Rough ER → Smooth ER → Golgi → Transport Vesicle → Plasma Membrane
  • B: Nucleus → Rough ER → Golgi → Transport Vesicle → Plasma Membrane
  • C: Rough ER → Golgi → Transport Vesicle → Plasma Membrane
  • D: Smooth ER → Golgi → Transport Vesicle → Plasma Membrane

Explanation

As described in Figure 6.15, membranes and proteins produced by the Rough ER move via transport vesicles to the Golgi apparatus for further processing and sorting. From the Golgi, transport vesicles then carry these materials to the plasma membrane for secretion, often through exocytosis.
