Why is the RER close to the nucleus?

The proximity of the rough ER to the cell nucleus gives the ER unique control over protein processing. The rough ER is able to rapidly send signals to the nucleus when problems in protein synthesis and folding occur and thereby influences the overall rate of protein translation.

Is the RER connected to the nucleus?

Rough ER (RER) was also mentioned in the section on ribosomes and is very important in the synthesis and packaging of proteins. Ribosomes are attached to the membrane of the ER, making it “rough.” The RER is also attached to the nuclear envelope that surrounds the nucleus.

How do the rough ER and nucleus work together?

How does the rough endoplasmic reticulum work with other organelles?

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 is rough endoplasmic reticulum different from smooth endoplasmic reticulum?

Smooth Endoplasmic Reticulum does not have ribosomes on its membrane. Rough Endoplasmic Reticulum possesses ribosomes attached to its membrane. It is organized of vesicles and tubules. It is organized of cisternae and a few tubules.

Why do the nucleus and endoplasmic reticulum work together?

The nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes. Mitochondria are responsible for ATP production; the endoplasmic reticulum modifies proteins and synthesizes lipids; and the golgi apparatus is where the sorting of lipids and proteins takes place.

What is the relationship between ribosomes and rough endoplasmic reticulum?

Rough ER is a host for ribosomes that continually attach to and detach from the ER surface. Essentially, the endoplasmic reticulum and ribosomes work together in order to synthesize proteins and have them transported to their final destination.

How is Rough ER different from smooth ER What functions do they perform in a cell?

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.

What is the difference between a rough endoplasmic reticulum and a smooth endoplasmic reticulum How does endoplasmic reticulum help in membrane biogenesis?

How is endoplasmic reticulum important for membrane biogenesis? – Biology Q&A….Differentiate between rough and smooth endoplasmic reticulum.
