Proteins are synthesized in the ribosomes, so they are either made on free ribosome in the cytoplasm or in the rough ER which is studded with ribosomes.

What is the membranous system that has rough and smooth varieties?

The endoplasmic reticulum is the membranous system that has rough and smooth varieties. The rough endoplasmic reticulum is studded with ribosomes that synthesize proteins, while the smooth endoplasmic reticulum plays a role in lipid metabolism and detoxification.


Name the two kinds of endoplasmic reticulum?

Two types of Endoplasmic Reticuli exists, the rough endoplasmic reticulum and the smooth endoplasmic reticulum. The rough endoplasmic reticulum is involved in the synthesis of proteins -{from through}- VIA the ribosomes embedded within its structure. The smooth endoplasmic reticulum is involved in the synthesis of lipids and steroids.


Distinguish between the smooth endoplasmic reticulum and the rough endoplasmic reticulum?

The rough endoplasmic reticulum is rough because of the ribosomes, or the things that make proteins in the cell, are attached to it, making it rough. The smooth one is smooth because their are no ribosomes attached to it.


What is essentially rough endoplasmic reticulum and important metabolically?

The rough ER (Endoplasmic Reticulum) has ribosomes on it. The Smooth ER does not. Ribosomes synthesize or make proteins.


What is the different between smooth endoplasmic reticulum and rough endoplasmic reticulum?

Smooth ER-synthesizes lipids and steroids, Rough ER-synthesizes proteins. Endoplasmic reticulum is rough when it contains Ribosomes.


How does rough ER differ from smooth ER in structures function?

Rough endoplasmic reticulum is studded with protein-producing ribosomes giving it a "rough" appearance, hence its name. It works in concert with the Golgi complex to target new proteins to their proper destinations. The rough endoplasmic reticulum is continuous with both the nuclear envelope and the smooth endoplasmic reticulum. Smooth endoplasmic reticulum has functions in several metabolic processes; it contains enzymes, and it stores calcium ions in muscle cells. Lipid synthesis takes place in the smooth endoplasmic reticulum. The smooth endoplasmic reticulum is continuous with the rough endoplasmic reticulum.


What is the nickname for a endoplasmic reticulum in a cell?

The ER. It depends on if you are referring to the smooth endoplasmic reticulum (smooth ER) or the rough endoplasmic reticulum (rough ER).


Which endoplasmic reticulum modifies and packages newly synthesized proteins.. A.the smooth reticulum B.the ribosomal reticulum C. the proteosomes reticulum D. the rough rerticulum E. the raised retic?

D. the rough endoplasmic reticulum modifies and packages newly synthesized proteins because it is studded with ribosomes that are responsible for protein synthesis. The smooth endoplasmic reticulum is involved in lipid metabolism and detoxification.

The cells that produce the oils that coat are hair contain a lot of what?

Rough endoplasmic reticulum & smooth endoplasmic reticulum Because hair contain protein called keratin. Proteins are made in rough ER. And lipids are produced by the smooth ER.


What is on rough endoplasmic reticulum that is not on smooth endoplasmic reticulum?

Ribosomes make RER "rough". SER is smooth because it has none. RER makes proteins because of the ribosomes and SER makes lipids.
