The smooth ER is involved in the synthesis of lipids, including cholesterol and phospholipids, which are used in the production of new cellular membrane. In certain cell types, smooth ER plays an important role in the synthesis of steroid hormones from cholesterol.

What are the three functions of smooth endoplasmic reticulum?
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. The smooth ER is distinguished from the other parts of the endoplasmic reticulum by the absence of membrane-bound ribosomes.
What is the function of smooth ER and smooth ER?
Definition of the Smooth ER
The main function of the smooth ER is to make cellular products like hormones and lipids. It also distributes those products throughout the cell and to places in the organism. The smooth ER also regulates and releases calcium ions and processes toxins.
Which of the following functions is performed by 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 would happen without the smooth ER?
The smooth ER has an important role in lipid and steroid synthesis, it is a storage for intracellular calcium as well. Without ER in the skeletal muscle fibers couldn't happen muscle contraction. In the absence of these cellular mechanisms the cell would probably die.
What is the mitochondria function?
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
What is the main function of the rough ER?
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 the role of SER in liver cells of vertebrates?
SER in the liver of vertebrates helps in detoxification . It metabolizes various toxic and poisonous substances such as drugs , aspirin , insecticides , petroleum products and pollutants . These toxic substances make their entry in animal's body through food , air , and water .
What organelle does smooth ER work with?
The vesicles often move to the Golgi apparatus for additional protein packaging and distribution. Smooth ER (SER) acts as a storage organelle. It is important in the creation and storage of lipids and steroids. Steroids are a type of ringed organic molecule used for many purposes in an organism.
What is the role of smooth endoplasmic reticulum in the liver cells of vertebrates animals?
(c) Smooth endoplasmic reticulum in liver cells of vertebrates helps in detoxification. It metabolizes various toxic or poisonous substances such as drugs, aspirin, insecticides (DDT), petroleum products and pollutants. These toxic substances make their entry in animal's body through food, air or water.
How does the smooth ER make lipids?
The smooth endoplasmic reticulum plays a major role in synthesizing lipids by means of enzymes embedded in these smooth membranes. ... In the reproductive organs, smooth ER in the cells produces the steroid hormones testosterone and estrogen.
Why do alcoholics have more smooth ER?
Large amounts of smooth ER are found in liver cells where one of its main functions is to detoxify products of natural metabolism and to endeavour to detoxify overloads of ethanol derived from excess alcoholic drinking and also barbiturates from drug overdose.
What is the difference in function between smooth and rough ER?
The main difference between these two terminologies is that the Smooth Endoplasmic Reticulum is known for stocking the lipids and proteins. ... Whereas, the Rough Endoplasmic Reticulum is bounded by the ribosomes and also stores proteins.
What is the difference of 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 is the function of SER Class 9?
The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. An organelle is a sub-unit within a cell that has a specialized function. The main function of the smooth ER is to make cellular products like hormones and lipids.
