Lipid Synthesis in SER — NEET Biology
✅ Asked in NEET 2018The smooth endoplasmic reticulum is the major site for synthesis of lipid. In animal cells lipid-like steroidal hormones are synthesised in SER.
The NTA specifically tests whether students know that the smooth endoplasmic reticulum (SER), NOT the rough endoplasmic reticulum (RER), is the major site for lipid synthesis. RER is studded with ribosomes and synthesizes proteins, while SER lacks ribosomes and handles lipid and steroid hormone synthesis. Students commonly confuse the two organelles because they focus on remembering that RER makes proteins without clearly distinguishing SER's unique role in lipid metabolism. To score correctly: RER = protein synthesis; SER = lipid and steroid hormone synthesis. This distinction is fundamental to cell biology and appears frequently in NEET questions testing organelle structure-function relationships.
