What is RER and its function?
rough endoplasmic reticulum (RER), series of connected flattened sacs, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that plays a central role in the synthesis of proteins.
What happens when rough ER is damaged?
Protein Folding in the Rough ER Misfolded proteins may not function properly, and this malfunction can even cause human disease.
What is the difference between ER and RER?
Additional Information: -Ribosomes are the protein factory of the cell hence RER functions for protein synthesis….Complete answer:
| Rough Endoplasmic Reticulum (RER) | Smooth Endoplasmic Reticulum (SER) |
|---|---|
| They are generally found in pancreatic cells. | They are generally found in adipose cells. |
Why does RER appear rough?
Rough Endoplasmic Reticulum (RER) appears rough because of the presence of ribosomes on it. Ribosomes are sites for biological protein synthesis. Polyribosomes are aggregation of several ribosomes held together by a string of mRNA.
How is RER involved in the production of enzymes?
The Rough Endoplasmic Reticulum(RER) is involved in the production of proteins. The ribosomes are the actual sites for protein synthesis. The ribosomes attached to the RER are involved in the synthesis of proteins that are meant to be transported outside the cell (ie., secreted) like several enzymes.
What is difference between SCR and RER?
The most basic difference between RER and SER is the presence of ribosomes. When ribosomes attach to the surface of an ER, it gives a characteristic rough appearance; hence it is called Rough ER. On the other hand, a smooth ER does not have ribosomes on its surface. It possesses ribosomes attached to its membrane.
What is R and SER?
Differences betweeen SER and RER: Rough Endoplasmic Reticulum (RER) Smooth Endoplasmic Reticulum (SER) It possesses ribosomes attached to its membrane.
What would happen if the smooth ER stopped working?
It plays an important role in lipid and steroid synthesis, it is a storage for intracellular calcium as well and the smooth ER was damaged, the cell would no longer be able to produce ribosomes which are needed to make proteins.
What is the difference between SCR and RER?
What is difference between nucleus and nucleolus?
The nucleolus is the distinct structure present in the nucleus of eukaryotic cells….Difference Between Nucleus and Nucleolus.
| Nucleus | Nucleolus |
|---|---|
| Bound by the nuclear envelope | It has no limiting membrane |
| It contains chromosomes. | It does not hold any chromosomes |
| It is rich in DNA, the genetic material | It is rich in RNA |
Where does RER occur in both animal and plant cells?
RER occurs in both animal and plant cells. endoplasmic reticulumEndoplasmic reticulum, a continuous membrane system in eukaryotic cells that plays an important role in the biosynthesis, processing, and transport of proteins and lipids.Encyclopædia Britannica, Inc.
Which is a function of the endoplasmic reticulum ( RER )?
The RER is generally a series of connected flattened sacs. It plays a central role in the synthesis and export of proteins and glycoproteins and is best studied in the secretory cells specialized in these functions. The rough endoplasmic reticulum (RER) has rows of knobs called ribosomes on its surface.
How does protein translation take place in the RER?
Once bound to the RER, the signal recognition particle dissociates, and protein translation continues. The newly formed protein then either becomes embedded in the RER membrane, in the case of a transmembrane protein, or is transmitted into the RER lumen via a translocon channel, in the case of a water-soluble protein.
What happens when collagen is misfolded in the RER?
For example, the accumulation of misfolded collagen proteins in the RER, owing to mutations in collagen-encoding genes, underlies various inherited skeletal disorders, including spondyloepimetaphyseal dysplasia, which is characterized by abnormal bone growth, weak joints, and susceptibility to joint dislocation.
