Question

Endoplasmic reticulum passes its products to the Golgi complex through which of the following?

• A. Simple diffusion
• B. Direct communication
• C. Transition vesicles
• D. Both B and C

Answer 1

Answer: (D)

Both B and C

A Golgisome has a central stack of 4-8 curved but parallel membrane-lined narrow sacs called as cisternae. They are similar to smooth endoplasmic reticulum. Cisternae bear a network of tubules and vesicles on their outer edges. Golgi apparatus receives materials from the cytosol and endoplasmic reticulum in the form of transitional vesicles. The movement may occur through vesicles that bud off from one cisternal edge to the next and so on. The movement of proteins and membranes between the endoplasmic reticulum and Golgi complex can be through direct contact also without involving any vesicles and diffusion process.

Thus, the correct answer is option D.
