Select the correct matching in the following pairs.                                                                           

A)  Smooth ER-Oxidation of phospholipids

B)  Smooth ER-Synthesis of lipids

C)  Rough ER-Synthesis of glycogen

D)  Rough ER-Oxidation of fatty acids

Correct Answer: B

Solution :

                Smooth ER- synthesis of lipids is correct match. Endoplasmic Reticulum (ER) is a network of tubules and flattened sacs in the cell. It is responsible of manufacturing and packaging system. There are two regions of ER as (i) Rough Endoplasmic Reticulum (RER) It contains ribosomes on its membrane so it synthesises only proteins and also transfer them wherever these are required. (ii) Smooth Endoplasmic Reticulum (SER) it is smooth because of lack of ribosomes around its membrane. It is involved in the synthesis and storage of lipids, fats, sterols and glycogen, etc.
