Question

The endoplasmic reticulum is involved in

• A. Proteolysis
• B. Peptide bond formation
• C. Both A and B
• D. Fatty acid and cholesterol synthesis

Answer 1

The correct option is D Fatty acid and cholesterol synthesis

Endoplasmic reticulum (ER) is the membrane bound organelle. It is of two types rough endoplasmic reticulum and smooth endoplasmic reticulum.Endoplasmic reticulum function is for the synthesis of lipids, synthesis of proteins, transportation of molecules to the cell membrane for export but not for the production of ribosomes. It is done by the nucleolus present within the nucleus.

Hence, the correct answer is 'Fatty acid and cholesterol synthesis'.
