How does the endoplasmic reticulum and the nucleus work together?

The endoplasmic reticulum (ER) is a large membrane-bound compartment spread throughout the cytoplasm of eukaryotic cells. It surrounds the nucleus as a double membrane bilayer and acts as a barrier to selectively control transport of molecules into and out of the nucleus (Fig. 1A,B).

What is the relationship between the nucleus nucleolus ribosomes and the rough endoplasmic reticulum?

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.

How does the nucleus rough endoplasmic reticulum and Golgi apparatus work together?

Working with the Rough ER The Golgi complex works closely with the rough ER. When a protein is made in the ER, something called a transition vesicle is made. This vesicle or sac floats through the cytoplasm to the Golgi apparatus and is absorbed.

Are the nucleus and ER connected?

Structurally, the endoplasmic reticulum is a network of membranes found throughout the cell and connected to the nucleus. The membranes are slightly different from cell to cell and a cell’s function determines the size and structure of the ER.

What is the difference between smooth ER and rough ER?

The main difference between these two terminologies is that the Smooth Endoplasmic Reticulum is known for stocking the lipids and proteins. It is not bounded by ribosomes. Whereas, the Rough Endoplasmic Reticulum is bounded by the ribosomes and also stores proteins.

What is the relationship between ribosomes and rough endoplasmic reticulum ER )?

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 do ribosomes and rough ER work together?

What is the relationship between ER and Golgi apparatus?

Golgi apparatus is the factory which receives proteins from the ER. It is found in the exit root of the ER. From the ER, mature proteins are transported into the Golgi apparatus. This transportation occurs by small vesicles called COPII-coated transported vesicles, which exit from ER exit sites.

How are rough endoplasmic reticulum and Golgi related?

The Golgi apparatus receives proteins and lipids (fats) from the rough endoplasmic reticulum. It modifies some of them and sorts, concentrates and packs them into sealed droplets called vesicles.

What is the role of the rough endoplasmic reticulum?

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.
