How do the two types of endoplasmic reticulum differ?
The ER can be classified in two functionally distinct forms: smooth endoplasmic reticulum (SER) and rough endoplasmic reticulum (RER). The morphological distinction between the two is the presence of protein-synthesizing particles, called ribosomes, attached to the outer surface of the RER.
What is the difference between a rough endoplasmic reticulum and a smooth endoplasmic reticulum How does endoplasmic reticulum help in membrane biogenesis?
How is endoplasmic reticulum important for membrane biogenesis? – Biology Q&A….
| Rough Endoplasmic Reticulum (RER) | Smooth Endoplasmic Reticulum (SER) |
|---|---|
| It possesses ribosomes attached to its membrane. | It does not have ribosomes on its membrane. |
| Formed of cisternae and a few tubules. | Formed of vesicles and tubules. |
What is the difference between the rough and smooth endoplasmic reticulum quizlet?
What is the difference between rough endoplasmic reticulum and smooth endoplasmic reticulum? Rough endoplasmic reticulum is covered in ribosomes and is involved in the synthesis and production of proteins. Smooth endoplasmic reticulum has no ribosomes and is involved in the production of enzymes and lipids.
What is the function of SER and RER?
Introduction on Rough and Smooth Endoplasmic Reticulum
| RER-Rough Endoplasmic Reticulum | SER-Smooth Endoplasmic Reticulum |
|---|---|
| They are found near the nucleus of the cell. | They are found away from the nucleus in the cell. |
| Their function is to synthesize proteins. | Their function is to synthesize lipids. |
What do SER and RER have in common?
Explanation: The smooth endoplasmic reticulum (SER) is smooth, and the rough endoplasmic reticulum (RER) is rough. Both the SER and RER are large continuous sheets of membrane that fold back on themselves to form an enclosed space (lumen).
What is difference between RER and SER Class 9 in points?
The main difference between the rough endoplasmic reticulum and smooth endoplasmic reticulum is that RER consists of ribosomes that are responsible for its rough nature and synthesis of protein. It plays a central role in protein synthesis. It plays an important role in lipid synthesis. It is structurally more stable.
What is difference between RER and SER?
Smooth ER is derived from rough endoplasmic reticulum by sacrificing the ribosomes, whereas Rough ER originates from the nuclear membrane. The main difference between the SER and RER is the presence of ribosomes, as SER does not consist of ribosomes but RER consists of ribosomes.
What’s the main difference between rough and smooth ER?
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 difference between rough and smooth ER?
The main difference between these two terminologies is that the Smooth Endoplasmic Reticulum is known for stocking the lipids and proteins. It is not bounded by ribosomes. Whereas, the Rough Endoplasmic Reticulum is bounded by the ribosomes and also stores proteins.
What are the major differences between rough and smooth endoplasmic reticulum?
What is the function of RER and SER Class 9?
2)Certain enzymes present in SER synthesise fat,steroids,cholesterol. 3)RER help in transport of protein which are synthesised by ribosomes on their surface. 5)It function as cytoplasmic framework providing a surface for some of the biochemical activities of the cell.
What are the similarities between rough and smooth ER?
Both rough ER and smooth ER have the same types of membranes but they have different shapes. Rough ER looks like sheets or disks of bumpy membranes while smooth ER looks more like tubes. Rough ER is called rough because it has ribosomes attached to its surface.
What can you use for endoplasmic reticulum?
The endoplasmic reticulum produces both lipids and proteins for the membrane of the cell. These lipids and proteins are also used to compose other parts of the cell such as vacuoles, the cell membrane, the Golgi apparatus, lysosomes, and secretory vesicles. There are two different portions of the ER – the rough ER and the smooth ER.
What is an example of an endoplasmic reticulum?
endoplasmic reticulum. The endoplasmic reticulum is defined as a series of folded membranes in the cells which are associated with protein synthesis, storage and the movement of cellular materials. An example of the endoplasmic reticulum is the place that steroids are stored in the cells for later use.
What are analogies for endoplasmic reticulum?
The ER is like a massive shipping facility that folds, packages, and exports proteins to destinations inside and outside of the cell. Hence it can be an analogy for endoplasmic reticulum.
What is the function of the rough endoplasmic reticlum?
Rough Endoplasmic Reticulum Function: The majority of the functions of rough ER is associated with protein synthesis. Rough endoplasmic reticulum also plays a vital role in protein folding. Also ensures quality control (regarding correct protein folding). The second most important function after protein synthesis and protein folding is protein sorting.
