Question

The smooth endoplasmic reticulum is well developed in the cells, which synthesize

• A. Steroids and lipids
• B. Carbohydrates
• C. Proteins
• D. All of the above

Answer 1

The correct option is A Steroids and lipids

The endoplasmic reticulum is of two types on the basis of present or absence of ribosome. If ribosome is attached with the endoplasmic reticulum, called as rough endoplasmic reticulum due to the rough surface. If ribosome is absent , called as smooth endoplasmic reticulum. The smooth endoplasmic reticulum plays a major role in synthesizing lipids by means of enzymes embedded in these smooth membranes. It produces the phospholipids and cholesterol used in membrane formation, and along with the membrane proteins produced by the rough Endoplasmic reticulum, it can synthesize more membrane for itself, for the Golgi complex, the cell membrane, lysosomes, and others.

Therefore, the correct answer is option A.
