Question

Suggest which among the following is not a function attributed to endoplasmic reticulum?

• A. Detoxification of poisons and drugs
• B. Digestion/ egestion of foreign materials outside the cell
• C. Manufacture of fat and lipid molecules
• D. Biogenesis of membrane proteins

Answer 1

Answer: (B)

Digestion/ egestion of foreign materials outside the cell

The endoplasmic reticulum is involved in the detoxification of the poisons and the drugs. This is the main function of the endoplasmic reticulum in the liver. The manufacturing of the lipids and fat molecules take place in the smooth ER. The membrane proteins are synthesised on the ribosomes which are present on the surface of the ER. The digestion and egestion of the foreign materials which enter the cells take place in the lysosomes.

Thus, the correct answer is option B.
