Solution
Verified by Toppr

  • When ribosomes are present in the membrane of the endoplasmic reticulum it is called the rough endoplasmic reticulum.
  • RER is abundantly found in the cells that actively synthesize proteins. The synthesis of lipids takes place in the smooth endoplasmic reticulum.
Thus, the correct answer is option E.
