E)All of the above.

Question

Quizplus · Accepted Answer

Bound ribosomes are attached to the endoplasmic reticulum (ER) and generally synthesize membrane proteins and secretory proteins that are transported to various organelles or the cell membrane for secretion. They are not enclosed in their own membrane and are not structurally different from free ribosomes. The most common location for bound ribosomes is the cytoplasmic surface of the endoplasmic reticulum. Therefore, option C is the correct statement that characterizes bound ribosomes.
