Essentially rough endoplasmic reticulum important metabolically?
The rough endoplasmic reticulum (RER) plays a crucial role in protein synthesis and processing by hosting ribosomes on its surface, which synthesize proteins that are essential for cell function and metabolism. The RER also aids in the folding and modification of proteins before they are transported to their final cellular destinations. In this way, the RER is integral to metabolic processes within cells.
How many rough endoplasmic reticulum are in a cell?
The number of rough endoplasmic reticulum (RER) in a cell can vary depending on the cell type and its function. Cells that are actively involved in protein synthesis and secretion, such as pancreatic cells or plasma cells, may have a higher number of RER compared to other cell types.
What performs the same function of smooth er?
The rough endoplasmic reticulum (RER) performs similar functions to the smooth endoplasmic reticulum (SER) in terms of protein synthesis and modification. However, the RER has ribosomes attached to its surface, giving it a "rough" appearance, whereas the SER lacks ribosomes and is involved in lipid metabolism, detoxification, and storage of calcium ions.
Why is RER rough?
The Real Exchange Rate (RER) can be considered rough because it reflects the relative price levels between two countries and can fluctuate due to various factors such as inflation rates, productivity changes, and exchange rate movements. These factors can make it challenging to precisely determine the true purchasing power parity between two currencies, leading to a rough estimate in RER calculations.
What is the definition of rough endoplasmic reticulum?
Rough endoplasmic reticulum, (RER),an organelle composed of an interconnected network of internal membranes within eukaryotic cells; rough ER is associated with ribosomes, whereas smooth ER lacks ribosomes.
What do RER do in the animal cell?
Protein synthesis is main function of RER in animal cells .
What are the main function of cell?
NUCLEAS AND MITOCHONDRIA AND RER/SER
Are ribosomes always attached to the RER?
No, ribosomes are not always attached to the rough endoplasmic reticulum (RER). While ribosomes are primarily found on the surface of the RER, where they synthesize proteins destined for secretion or membrane insertion, free ribosomes also exist in the cytoplasm. These free ribosomes synthesize proteins that function within the cytosol. The attachment of ribosomes to the RER is a dynamic process that occurs based on the specific needs of the cell.
When was RER A created?
RER A was created in 1977.
What is the ''RER''?
That is The Rough Endoplasmic Reticulum in a cell. (RER)
What does endoplasmic recticulum do in a animal cell?
It's function is to make proteins. The RER has ribosomes embedded in its' membrane and that is what produces its' rough appearance.
When was RER B created?
RER B was created in 1977.
When was RER C created?
RER C was created in 1979.
When was RER D created?
RER D was created in 1987.
When was RER E created?
RER E was created in 1999.
What is the role of the membrane in the rough endoplasmic reticulum?
The membrane of the RER contains ribosomes. This is what makes the membrane "rough". The function of the ribosomes is to produce proteins.
What is a nickname for the rer?
A common nickname for the RER (Réseau Express Régional) in France, particularly in the Paris region, is "le RER." Sometimes, it's informally referred to as "le train de banlieue," meaning "suburban train," as it connects central Paris to its suburbs. Each line of the RER is also often referred to by its letter designation, such as "RER A" or "RER B."
