Does rough endoplasmic reticulum give rise to smooth endoplasmic reticulum?
Does rough endoplasmic reticulum give rise to smooth endoplasmic reticulum?
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.
Which makes the smooth endoplasmic reticulum to a rough one?
The smooth endoplasmic reticulum (SER) is distinguished from the rough endoplasmic reticulum (RER), the other basic type of endoplasmic reticulum, by its lack of ribosomes, which are protein-synthesizing particles that can be found attached to the outer surface of the RER to give the membrane its “rough” appearance.
Who gives rise to SER?
Difference between Smooth and Rough Endoplasmic Reticulum
| Rough Endoplasmic Reticulum (RER) | Smooth Endoplasmic Reticulum (SER) |
|---|---|
| It participates in the synthesis of enzymes and proteins. | Synthesises glycogen, lipids and steroids. |
| It helps in the formation of lysosomes. | Gives rise to Spherosomes/ Oleosomes |
What is the origin of smooth endoplasmic reticulum?
From the results of this study, it is evident that there are two sources of origin of these membranous systems, namely, the nuclear envelope and Golgi complex. At first the smooth endoplasmic reticulum appears in long arrays immediately beneath the plasma membrane.
Are the rough and smooth endoplasmic reticulum connected?
Rough and smooth ER are typically connected to one another so that the proteins and membranes made by the rough ER can freely move into the smooth ER for transport to other parts of the cell.
What is rough endoplasmic reticulum and smooth endoplasmic reticulum?
Rough ER (RER) is involved in some protein production, protein folding, quality control and despatch. It is called ‘rough’ because it is studded with ribosomes. Smooth E R (SER) is associated with the production and metabolism of fats and steroid hormones.
What does rough endoplasmic reticulum do?
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
How do rough and smooth ER compare structurally and functionally?
Describe the structural and functional distinctions between rough and smooth ER. The primary distinction between rough and smooth ER is the presence of bound ribosomes on the rough ER. The smooth ER also functions in detoxification, carbohydrate metabolism, and storage of calcium ions.
Why is rough endoplasmic reticulum important?
The rough ER, studded with millions of membrane bound ribosomes, is involved with the production, folding, quality control and despatch of some proteins. Smooth ER is largely associated with lipid (fat) manufacture and metabolism and steroid production hormone production. It also has a detoxification function.
