What is rough endoplasmic reticulum and its 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. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
What is function of smooth endoplasmic reticulum?
Smooth Endoplasmic Reticulum Function:
Smooth ER is responsible for the synthesis of essential lipids such as phospholipids and cholesterol. Smooth ER is also responsible for the production and secretion of steroid hormones. It is also responsible for the metabolism of carbohydrates.
What are the features 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 function of sER?
sER is a membrane-bound network of tubules (see Figs. 1-1 and 1-3) without surface ribosomes. sER is not involved in protein synthesis. Its main function is the synthesis of lipids, steroids, and carbohydrates, as well as the metabolism of exogenous substances, such as drugs or toxins.
What is difference between the smooth and rough ER?
The most basic difference between RER and SER is the presence of ribosomes. When ribosomes attach to the surface of an ER, it gives a characteristic rough appearance; hence it is called Rough ER. On the other hand, a smooth ER does not have ribosomes on its surface. It possesses ribosomes attached to its membrane.
What are the 5 functions of endoplasmic reticulum?
It is composed of two forms: RER and SER. Smooth endoplasmic reticulum, SER, is involved in the synthesis of fat and steroid hormones. Smooth endoplasmic reticulum helps in the muscle contraction by the release and uptake of calcium ions. Rough endoplasmic reticulum, RER, provides the surface for protein synthesis.
What are 3 jobs of the smooth ER?
Its main functions are the synthesis of lipids, steroid hormones, the detoxification of harmful metabolic byproducts and the storage and metabolism of calcium ions within the cell.
What is endoplasmic reticulum made of?
The ER is often an extensive, 3-dimensional network of intracellular membranes. It is formed of three types of elements: Cisternae, tubules, and vesicles.
What are the 3 main functions of the endoplasmic reticulum?
The endoplasmic reticulum (ER) serves important functions particularly in the synthesis, folding, modification, and transport of proteins.
What do the SER and RER have in common?
Both the SER and RER are large continuous sheets of membrane that fold back on themselves to form an enclosed space (lumen).
What is the difference between rough ER and smooth ER quizlet?
Rough endoplasmic reticulum is covered in ribosomes and is involved in the synthesis and production of proteins. Smooth endoplasmic reticulum has no ribosomes and is involved in the production of enzymes and lipids.
What are the 2 types of endoplasmic reticulum?
Spreading throughout some cells, the ER becomes flattened into thin pancakes called lamellae, which are very prominent in cells carrying out a lot of protein synthesis. Under the electron microscope, it is possible to distinguish two types of endoplasmic reticulum: rough and smooth.
Where is smooth ER located?
smooth endoplasmic reticulum (SER), meshwork of fine disklike tubular membrane vesicles, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that is involved in the synthesis and storage of lipids, including cholesterol and phospholipids, which are used in the production of new cellular …
Does the smooth ER detoxify drugs?
A smooth endoplasmic reticulum in the liver performs function in the detoxification of harmful chemicals and drugs.
Where is endoplasmic reticulum located?
cytoplasm
The endoplasmic reticulum (ER) is a network of membrane-enclosed tubules and sacs (cisternae) that extends from the nuclear membrane throughout the cytoplasm (Figure 9.1). The entire endoplasmic reticulum is enclosed by a continuous membrane and is the largest organelle of most eukaryotic cells.
What is endoplasmic reticulum in simple words?
Listen to pronunciation. (EN-doh-PLAZ-mik reh-TIH-kyoo-lum) A network of sac-like structures and tubes in the cytoplasm (gel-like fluid) of a cell. Proteins and other molecules move through the endoplasmic reticulum.
What is the difference between smooth ER and rough ER?
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.
What is the main difference between the rough and smooth endoplasmic reticulum?
What is the structural difference between rough endoplasmic reticulum ER and smooth ER?
What is smooth ER and rough ER?
Smooth Endoplasmic Reticulum does not have ribosomes on its membrane. Rough Endoplasmic Reticulum possesses ribosomes attached to its membrane. Organized. It is organized of vesicles and tubules.
How many endoplasmic reticulum are in a cell?
There are two types of endoplasmic reticulum: rough endoplasmic reticulum (rough ER) and smooth endoplasmic reticulum (smooth ER). Both types are present in plant and animal cells.
What are the three functions of SER?
What is the function of SER?
- Synthesises glycogen, lipids and steroids.
- It helps in the formation of spherosomes/ Oleosomes.
- Provides vesicles for cis-face of Golgi apparatus.
How do you clean your body cells?
While detox diets have a seductive appeal, your body is fully equipped to handle toxins and other unwanted substances.
- Limit alcohol.
- Focus on sleep.
- Drink more water.
- Reduce your intake of sugar and processed foods.
- Eat antioxidant-rich foods.
- Eat foods high in prebiotics.
- Decrease your salt intake.
- Stay active.
How does the smooth ER detoxify the liver?
The detoxification process is performed by the help of the smooth endoplasmic reticulum in liver cells. Liver cells are composed of enzymes that catalyse a number of reactions and can make lipid-soluble drugs and metabolic wastes which are soluble in water, so that these can easily be passed out from the body.
