Question

Which of the following divides the intracellular space into two distinct compartments?

• A. Endoplasmic reticulum
• B. Cell membrane
• C. Plasma membrane
• D. None of the above

Answer 1

Answer: (A)

Endoplasmic reticulum

The endoplasmic reticulum is a network of membranous tubules within the cytoplasm of a eukaryotic cell. It is occupied close to the outer nuclear membrane. It usually has ribosomes attached and is involved in protein and lipid synthesis. The endoplasmic reticulum divides the intracellular space into two distinct compartments, viz. luminal and extra-luminal.

So, the correct answer is option A.
