Endoplasmic Reticulum
(Smooth and Rough)
The Endoplasmic Reticulum is a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells. The Endoplasmic Reticulum works with every organelle in the cell and it transports proteins, lipids and other materials through the cell. It also carries out the metabolism of drug detoxification, carbohydrates, steroid metabolism and the attachment of receptors on cell membrane proteins.
Two types of Endoplasmic Reticulum
SMOOTH ENDOPLASMIC RETICULUM
The Smooth Endoplasmic Reticulum is associated with the production and metabolism of fats. It is called ‘smooth’ because it is not studded with ribosomes and it is associated with smooth slippery fasts and its functions differ. The smooth ER is involved in the synthesis of lipids which are used in the production of new cellular membrane. In certain cell types, smooth ER plays an important role in the synthesis of steroid hormones from cholesterol.
ROUGH ENDOPLASMIC RETICULUM
The Rough Endoplasmic Reticulum is involved in the protein folding, protein production, quality control and despatch. It is called ‘rough’ because it is studded with ribosomes. Rough ER lies adjacent to the cell nucleus, and its membrane is continuous with the outer membrane of the nuclear envelope.
A cell with no ER will not be able to transport protein into other organelles. Without proteins, membranes will not operate and no one is responsible for building and repairing of body tissues. Without the Endoplasmic Reticulum, there will be no proteins and you will not be able to survive!

The only reason why the rough ER is important is all because of the Ribosome! You are like a maid to us. You store us, pack us and transport us so we can do the real work in order to keep the cell working properly. Without the Ribosome there would be no rough ER and no point for you to take up space and clog the cell. We Ribosomes are vital and must be top priority to ensure proper cell growth. That is why you were almost single-handily made just so we could be easily transported and moved to the other, more useful organelles that need our help! ~ This is Jason, I don't know why it is listed as unknown.
