Differentiate between rough and smooth endoplasmic reticulum. How is endoplasmic reticulum important for membrane biogenesis?

Explanation

(a) For differences in tough ER and smooth ER see Table 2.13. Membranes grow as newly synthesized proteins and lipids aer inserted into existing membrane in endoplasmic reticulum (ER). Glycolisation of proteins of proteins on the membrane is started in endoplasmic reticulum (ER). Glycolisation of proteins of te membrane is started in RER but completed in Golgi apparatus. Glycolisation of proteins of the membrane is started in PER but completed in Golgi apparatus. Glycolisation of lipids of the membrane occurs in Golgi apparatus. Flow of membrane occurs in the following manner.
