The RER contracts and expands to allow blood cells and the homoblougn to cooperate with the lungs. After that the bolus in your stomach goes downwards as the "trap door" of your stomach opens. Then, it goes in the large intestine and out of your buttocks.
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.
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.
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.
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.
rough endoplasmic reticulum[RER] has ribosomes attached to it giving a rough appearance thereby deriving its name. smooth endoplasmic reticulum[SER] is devoid of ribosomes. RER- involved in protein synthesis as ribosomes are concerned with protein synthesis. SER-concerned with lipid synthesis in intestinal cells& with steroid formation in adrenals
Protein synthesis is main function of RER in animal cells .
NUCLEAS AND MITOCHONDRIA AND RER/SER
RER A was created in 1977.
That is The Rough Endoplasmic Reticulum in a cell. (RER)
RER B was created in 1977.
RER C was created in 1979.
RER D was created in 1987.
RER E was created in 1999.
It's function is to make proteins. The RER has ribosomes embedded in its' membrane and that is what produces its' rough appearance.
The membrane of the RER contains ribosomes. This is what makes the membrane "rough". The function of the ribosomes is to produce proteins.
Auber - Paris RER - was created in 1971.
Champigny - Paris RER - was created in 1859.
