How To Have More Of A Pointer Nose
The endoplasmic reticulum is a membrane system whose structure consists of a network of flattened saccules or cisterns, vesicles and sacs globose or sinuous tubules that extend throughout the cytoplasm and communicate with the outer nuclear membrane. Inside those bags flat is a space called lumen storing substances. There are two classes of endoplasmic reticulum: rough (with ribosomes attached) and smooth (ribosome-associated free).
Its primary function is the synthesis of proteins, the synthesis of lipid membrane constituents and participation in processes detoxification of the cell.
