What is the function of the rough endoplasmic reticulum?
The rough endoplasmic reticulum is a membranous structure that associates closely with the nucleus. Embedded in the membrane of the structure are ribosomes, this is what gives the "rough" appearance. RNA passes through the ribosomes where its sequence of nucleic acid codes for specific amino acids to be joined up in a specific order. The route through the ribosomes for the amino acid takes them into the membranes of the reticulum where they can be kept together. They are then moved of in vesicles formed from the ER membranes to the Golgi Apparatus to be packaged and processed.
The rough ER is involved in protein synthesis. There are ribosomes attached to the surface, giving it a bumpy or 'rough' appearance. Ribosomes are the site of protein synthesis.
It transports material through the Cell and produces proteins in
sacks called cistren or cisternae which are sent to the Golgi body
for export, or for insertion into the Cell membrane.
The rough endoplasmic reticula synthesize proteins. For more detailed information - see the related link to Wikipedia.
Endoplasmic reticulum is like a transport and manufacturing pipeline, for many biochemical compounds. Endoplasmic reticulum function is dependent on its type. There are three types of endoplasmic reticulum, which are: Rough Endoplasmic Reticulum (RER) Smooth Endoplasmic Reticulum (SER) Sarcoplasmic Reticulum (SR)
What is on the surface of rough endoplasmic reticulum that is not on the surface of smooth endoplasmic reticulum?
Rough endoplasmic reticulum (RER) has the following functions:- *Rough Endoplasmic Reticulum have ribosomes attached to their surface that synthesize proteins for the cell. Rough ER transports these proteins to the regions in the cell where it is needed. *Enzymes of lysosome are also produced by the Rough Endoplasmic Reticulum
The rough and smooth endoplasmic reticulum are both packaging systems. The smooth endoplasmic reticulum creates and stores steroids. The rough endoplasmic reticulum is important to the synthesis and storage of proteins. The ribosomes produce the amino acid chain while attached to the rough endoplasmic reticulum. The endoplasmic reticulum then pinches off a vesicle for transport.
