What is the purpose of the endoplasmic reticulum in an animal cell?
The endoplasmic reticulum (ER) is a large, dynamic structure that serves many roles in the cell including calcium storage, protein synthesis and lipid metabolism. The diverse functions of the ER are performed by distinct domains; consisting of tubules, sheets and the nuclear envelope.
Why is rough er important?
The function of the rough ER is to provide a place so ribosomes can produce proteins, and proteins are one of the most important things in a cell. Also, the rough ER is involved in the transportation of proteins to the Golgi apparatus. Additionally, the rough ER makes certain enzymes that are vital to the cells.
What are some facts about endoplasmic reticulum?
Endoplasmic Reticulum. Endoplasmic reticulum is a network of membranes or tubes in a cell through which materials move. As an organelle in a eukaryotic cell (complex cells having nuclei and other organelles), it is involved with the production of new proteins as well as with the movement of materials throughout the cell.
What are the functions of rough ER?
The rough ER’s main function is to help form and store proteins, while the smooth ER store lipids, a type of fat. The whole reason why it’s called “rough” is because the ribosomes attaching to it give it a “bumpy” or “rough” appearance.
What is role of endoplasmic reticulum in protein synthesis?
Though Smooth Endoplasmic Reticulum (SER) does not take part in protein synthesis unlike Rough Endoplasmic Reticulum (RER), it plays an important role in protein transportation. It regulates the transportation of proteins by acting as a transitional area for vesicles that transfer proteins to various locations.
What is the relationship between the Golgi and the ER?
The functioning of the Golgi apparatus and ER are both so closely linked to the lysosomes that together, these entities compose the endomembrane system. Interestingly, lysosomal formation relies on the joint contribution of the ER and Golgi. The Golgi is responsible for the formation of lysosomes.
