Question

Select the correct statement.

• A. RER has no ribosome but SER has ribosomes
• B. RER has ribosomes but SER has no ribosome
• C. RER is involved in the synthesis of lipids
• D. SER is involved in the synthesis of proteins

Answer 1

The correct option is B RER has ribosomes but SER has no ribosome

Endoplasmic reticulum (ER) is a membrane-bound network extending from the nuclear membrane to the plasma membrane. When ribosomes are found attached to the surface of the ER, it is called a rough endoplasmic reticulum (RER) and if there are no ribosome attached to it, it is called the smooth endoplasmic reticulum (SER).
Ribosomes on RER are involved in the synthesis of proteins. SER is involved in the synthesis of lipids.
