Question

Which of the following process takes place in endoplasmic reticulum?

• A. Lipid synthesis
• B. Channeling of biosynthetic processes
• C. Steroid synthesis
• D. All of the above

Answer 1

The correct option is D All of the above

Rough Endoplasmic Reticulum (RER) is abundant in cells engaged in active secretion. Proteins synthesized by ribosomes pass into the lumen of RER which acts as a channel for transport of secretory proteins. Endoplasmic reticulum without ribosomes is called as smooth endoplasmic reticulum (SER). SER occurs in cells engaged in producing a lot of lipids and steroids. SER also takes part in the synthesis of vitamins, carbohydrates and detoxification. Thus, the correct answer is option D.
