What is the endoplasmic reticulum function?
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. So the endoplasmic reticulum is an organelle that’s really a workhorse in producing proteins and substances needed by the rest of the cell.
What are different types of endoplasmic reticulum write their function?
the two types of endoplasmic reticulum are : rough endoplasmic reticulum: their main function is produce proteins in the cells and ribosomes are attached to their surface. smooth endoplasmic reticulum: their main function is to produce lipids and also detoxify toxins in the body in the liver and kidney cells.
What is endoplasmic reticulum structure?
The endoplasmic reticulum is the largest single structure in eukaryotic cells. It consists of a range of interconnected shapes, including sheets and tubules, and comprises a lumen enclosed by a membrane that is continuous with the membrane that surrounds the nucleus of the cell (Figure 1).
Is endoplasmic reticulum prokaryotic or eukaryotic?
Endoplasmic reticulum, microtubules, and the Golgi apparatus are unique to eukaryotic cells, and will not be found in prokaryotes.
What is endoplasmic reticulum main function Class 9?
Endoplasmic reticulum performs the following functions: It is responsible for the production and secretion of steroid hormones. It is also responsible for the synthesis of essential lipids such as phospholipids and cholesterol. It is responsible for the metabolism of carbohydrates.
Why is endoplasmic reticulum absent in prokaryotes?
in the prokaryotes the nuclear region is not fully developed or it is not bounded by the membrane so nucleoplasm has direct contact with the cytoplasm of the cell..
What is the function of endoplasmic reticulum 9?
What is endoplasmic reticulum for class 8th?
The endoplasmic reticulum (ER) is a large organelle composed of membranous sheets and tubules that start near the nucleus and stretch throughout the cell. The endoplasmic reticulum produces, packages, and secretes many of the products a cell creates.
What is the function of endoplasmic reticulum?
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.
What is the difference between the rough and smooth endoplasmic reticulum?
A cell’s endoplasmic reticulum (ER) contains a network of tubules and flattened sacs. The ER performs a number of functions in both plant and animal cells. Endoplasmic reticulum has two major regions: smooth endoplasmic reticulum and rough endoplasmic reticulum. Rough ER contains attached ribosomes while smooth ER does not.
Where does protein synthesis occur in the endoplasmic reticulum?
Protein synthesis occurs in the rough endoplasmic reticulum. Although translation for all proteins begins in the cytoplasm, some are moved into the ER in order to be folded and sorted for different destinations. Proteins that are translocated into the ER during translation are often destined for secretion.
What is the function of the ER in a cell?
The ER is the largest organelle in the cell and is a major site of protein synthesis and transport, protein folding, lipid and steroid synthesis, carbohydrate metabolism and calcium storage [1–7].
