Select the correct matching in the following pairs :

  1. Rough ER – Oxidation of fatty acids
  2. Smooth ER – Oxidation of phospholipids
  3. Rough ER – Synthesis of glycogen
  4. Smooth ER – Synthesis of lipids

Answer

(4) Smooth ER – Synthesis of lipids

Solution

As per NCERT, RER is frequently observed in cells actively involved in protein synthesis and secretion.

⇒ The smooth endoplasmic reticulum is the major site for synthesis of lipids; in animal cells lipid-like steroidal hormones are synthesised in SER.

∵ Oxidation of fatty acids occurs in mitochondria (and peroxisomes), and glycogen is not synthesised by RER.

∴ The correct pair is Smooth ER – Synthesis of lipids.

Answer: (4)
