Smooth ER is derived from rough endoplasmic reticulum by sacrificing the ribosomes, whereas Rough ER originates from the nuclear membrane. The main difference between the SER and RER is the presence of ribosomes, as SER does not consist of ribosomes but RER consists of ribosomes.

How does rough ER differ from smooth ER quizlet?
Rough endoplasmic reticulum is covered in ribosomes and is involved in the synthesis and production of proteins. Smooth endoplasmic reticulum has no ribosomes and is involved in the production of enzymes and lipids.
How is rough er different from smooth ER what function do they perform a cell?
Rough ER is different from smooth ER in having ribosomes (protein units ) on its surface. ... The Ribosomes present in RER are the structures responsible for making proteins which are further sent to the lumen . It is also responsible for making phospholipids which make up the membranes of cells. Hope that helps !
What is the difference between rough ER and smooth ER What is the ER doing that is different in each case?
Rough ER has ribosomes attached to it that make proteins and lipids. Smooth ER doesn't have ribosomes and can be used for storage and for making lipids.
What is the smooth ER quizlet?
smooth endoplasmic reticulum. collection of enzymes that perform specialized tasks, including synthesis of membrane lipids and the detoxification of drugs. endoplasmic reticulum. site where lipid components of the cell membrane are assembled, along with proteins and tother materials that are exported from the cell.
Which of the following functional differences between the rough and smooth ER is explained by the structural difference between them?
The difference between the rough endoplasmic reticulum and the smooth endoplasmic reticulum is that the rough endoplasmic reticulum contains ribosomes. The smooth endoplasmic reticulum does not contain ribosomes. The ribosomes are what give rough endoplasmic reticulum its characteristic "roughness."
What is the difference between rough ER and ribosomes?
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. It possesses ribosomes attached to its membrane.
What is one function of the smooth ER?
The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids. Cells that secrete these products, such as cells of the testes, ovaries, and skin oil glands, have an excess of smooth endoplasmic reticulum.
What are the functions of smooth ER?
Its main functions are the synthesis of lipids, steroid hormones, the detoxification of harmful metabolic byproducts and the storage and metabolism of calcium ions within the cell. The smooth ER is distinguished from the other parts of the endoplasmic reticulum by the absence of membrane-bound ribosomes.
What makes rough ER rough quizlet?
It is called 'rough' endoplasmic reticulum because it is studded on its outer surface (the surface in contact with the cytosol) with ribosomes. ... Rough ER is found throughout the cell but the density is higher near the nucleus and the Golgi apparatus.
What is a smooth ER simple definition?
smooth endoplasmic reticulum (SER), meshwork of fine disklike tubular membrane vesicles, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that is involved in the synthesis and storage of lipids, including cholesterol and phospholipids, which are used in the production of new cellular ...
What makes the rough ER rough?
Proteins are assembled at organelles called ribosomes. When proteins are destined to be part of the cell membrane or exported from the cell, the ribosomes assembling them attach to the endoplasmic reticulum, giving it a rough appearance.
What are the structural and functional differences between rough ER and smooth ER Why do cells of the testes and adrenal glands have large amounts of smooth ER?
Rough and smooth ER (endoplasmic reticulum) differ in that the rough ER has ribosomes on it. ... Smooth ER does not have ribosomes and is where steroids are made, which is why there is a lot of smooth ER in cells of the the adrenal gland and sex organs which produce steroid hormones such as estrogen and testosterone.
Do smooth ER have ribosomes?
Smooth endoplasmic reticulum lacks ribosomes and helps synthesize and concentrate various substances needed by the cell.
What is the main function of the Smooth Endoplasmic Reticulum quizlet?
One of the primary functions of the Smooth Endoplasmic Reticulum is to produce and move lipids, an essential component of a cell's outer membrane, and steroids.
Which of the following is a function of the rough ER?
Which of the following is a function of the rough endoplasmic reticulum? The rough ER synthesizes all proteins secreted from the cell; it also functions as the cell's "membrane factory" because integral proteins and phospholipids that form part of all cellular membranes are manufactured there.
