Difference Between Smooth and Rough ER | Structure …
3/1/2017 · Smooth ER, on the other hand, helps in the storage of proteins and lipids. The main difference between smooth and rough ER is that smooth ER lacks bound ribosomes whereas rough ER is bound with ribosomes.
The basic difference between Smooth and Rough ER is that smooth endoplasmic reticulum does not contain ribosomes so its surface is smooth and performs lipid synthesis function. While rough endoplasmic reticulum contains ribosomes which are small, round organelle, have a rough surface, and perform protein synthesis.
Difference between Smooth and Rough Endoplasmic Reticulum The most basic difference between RER and SER is the presence of ribosomes. When ribosomes attach to the surface of an ER, it gives a characteristic rough appearance hence it is called Rough ER. On the other hand, a smooth ER does not have ribosomes on its surface.
Smooth ER is more tubular than rough ER and forms an interconnecting network sub-compartment of ER. It is found fairly evenly distributed throughout the cytoplasm. It is not studded with ribosomes hence ‘smooth’ ER. Smooth ER is devoted almost exclusively to the manufacture of lipids and in some cases to the metabolism of them and associated products.
Endoplasmic Reticulum : The endoplamsic reticulum is a membranous organelle present in the cells of eukaryotic organisms. There are two types of endoplasmic reticulum : smooth and rough .
