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 |
A major site for synthesis of lipids is
1. RER
2. SER
3. symplast
4. nucleoplasm
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 |
4. | lipid and protein synthesising cells |
