Do the rough and smooth endoplasmic reticulum have the same function?
The rough ER, studded with millions of membrane bound ribosomes, is involved with the production, folding, quality control and despatch of some proteins. Smooth ER is largely associated with lipid (fat) manufacture and metabolism and steroid production hormone production. It also has a detoxification function.
What is the difference between SER and RER?
The most basic difference between RER and SER is the presence of ribosomes….Difference between Smooth and Rough Endoplasmic Reticulum.
| Rough Endoplasmic Reticulum (RER) | Smooth Endoplasmic Reticulum (SER) |
|---|---|
| Provides proteins and lipids for Golgi apparatus. | Provides vesicles for cis-face of Golgi apparatus. |
What do the nucleus and the smooth endoplasmic reticulum have in common?
The nucleus and the smooth endoplasmic reticulum both are membrane bound organelles and are connected into one continuous membrane.
What does rough endoplasmic reticulum do?
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
What are the functions of rough ER?
The rough ER’s main function is to help form and store proteins, while the smooth ER store lipids, a type of fat. The whole reason why it’s called “rough” is because the ribosomes attaching to it give it a “bumpy” or “rough” appearance.
What is the rough ER job?
Most endoplasmic reticulum found in cells is rough ER. Due to its affiliation with the ribosomes , the general function of rough ER is to isolate and transport the proteins that have been constructed at the ribosomes. Many of the proteins that are made within a cell are not needed within that cell, but are actually secreted out of the cell.
What are the characteristics of the endoplasmic reticulum?
The endoplasmic reticulum (ER) is a network of flattened sacs and branching tubules that extends throughout the cytoplasm in plant and animal cells. These sacs and tubules are all interconnected by a single continuous membrane so that the organelle has only one large, highly convoluted and complexly arranged lumen (internal space).
What does rough ER mean?
Rough Endoplasmic Reticulum Definition. The rough endoplasmic reticulum (rough ER) is a part of the endomembrane system of the cell and a subset of the endoplasmic reticulum (ER).
