The endomembrane system of a eukaryotic cell does not include:
1. Endoplasmic reticulum
2. Lysosome
3. Vacuole
4. Peroxisome
All the following are the part of a eukaryotic cell endomembranous system except:
1. Vacuole
2. Lysosome
3. Golgi complex
4. Mitochondria
Proteins that are to be used outside the cell are synthesized:
1. in the mitochondria
2. on the rough endoplasmic reticulum
3. on the smooth endoplasmic reticulum
4. on free ribosomes
Select the correct matching in the following pairs.
1. Smooth ER—Oxidation of phospholipids
2. Smooth ER—Synthesis of lipids
3. Rough ER—Synthesis of glycogen
4. Rough ER—Oxidation of fatty acids
SER and RER can be distinguished with its presence in
1. protein synthesising cells
2. protein and fat synthesising cells
3. carbohydrates and fat synthesising cells
3. lipid and protein synthesising cells

4. Chloroplasts
1. SER are the sites for lipid synthesis
2. RER has ribosomes attached to ER
3. SER is devoid of ribosomes
4. In prokaryotes, only RER is present
