What the function of endoplasmic reticulum?

Answer 1

Basically, it performs the synthesis and modification of proteins and their shipping to the Golgi for further modification (O-glycosylation, for instance ), then the Golgi is the shipping department of the cell.. The smooth ER has to do with the modification of lipids and carbohydrates, and detoxification of the cell.

----------------------------------------------------------------

The Endoplasmic Reticulum as a whole works to compartmentalize the cell by weaving into sheets all across the cell. The portions of the ER studded with ribosomes (labeled Rough) synthesize proteins while the portions without ribosomes (labeled Smooth) synthesize lipids. Basically, if you compare a cell to a city, the endoplasmic reticula are the roads in which materials can be processed and moved around inside of the cell.

It has ribosomes inside which make and sort proteins (also known as synthesis). Rough endoplasmic reticula synthesize proteins, while smooth endoplasmic reticula synthesize lipids and steroids, metabolize carbohydrates and steroids, and regulate calcium concentration, drug detoxification, and attachment of receptors on cell membrane proteins.

There are two parts of the endoplasmic reticulum; the smooth and the rough. The endoplasmic reticulum has several general functions, one being the facilitation of protein folding and the transport of synthesized proteins in cisternae. Only proteins that are folded properly are transported into the Golgi complex from the rough Endoplasmic Reticulum. The "ER" also attaches oligosaccharides in a process called Glycosylation. ( N-glycosylation ) 1. Proteins that are transported by the endoplasmic reticulum.

2. Glycosylation

3. Disulfide bond formation and rearrangement

4. Drug Metabolism

rough er is found through the cell

Answer 2

The rough ER is where proteins that will be exported outside of the cell are made and organized. Vesicles bud off from the Rough ER and will go to the Golgi and so on until the proteins are modified. ER also helps in detoxification.
