What are the three function of smooth endoplasmic reticulum?

What are the three function 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 endoplasmic reticulum and rough endoplasmic reticulum?

The rough ER, studded with millions of membrane bound ribosomes, is involved with the production, folding, quality control and despatch of some proteins. Smooth ER is largely associated with lipid (fat) manufacture and metabolism and steroid production hormone production. It also has a detoxification function.

What is the function of SER and RER respectively?

Explanation: SER= its function is to manufacture the fats moecules or lipids. RER=it function is to synthesis protines.

What is the function of SER in liver cells of vertebrates Class 9?

Class 9 Question Besides the usual function of synthesizing lipids and fatty acids, the SER in the liver detoxify drugs and convert them to less toxic substances which are then readily eliminated through the excretory organs.

What is the significance of presence of SER in liver cells?

The Smooth Endoplasmic Reticulum (SER) of liver cells detoxifies drugs and poisons present in the body. The liver cells detoxify harmful substances by a complex series of chemical reactions. SER releases some enzymes that make the poisons and drugs soluble to the cytosol and are easily excreted out.

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 between smooth and rough endoplasmic reticulum?

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 role of the smooth endoplasmic reticulum in the liver cells of vertebrates?

(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.

What is the role of endoplasmic reticulum in the liver cells of vertebrates?

Liver cells of some vertebrates have smooth endoplasmic reticulum which helps in detoxifying certain drugs and poison from the body.

What is the function of rough endoplasmic?

The rough endoplasmic reticulum is commonly associated with the function of synthesizing proteins and transporting protein molecules to different parts of the cell. The membrane of the rough ER is studded with ribosomes , which are components that produce proteins from their building blocks, amino acids.

What is the function of smooth ER?

The smooth ER is like an interconnected tubular network that may extend to the periphery of the cell. It is mainly responsible for production and metabolism of lipids. Smooth endoplasmic reticulum is assigned with various functions, that may vary with different types of cells.

What are diseases caused by endoplasmic reticulum?

Endoplasmic reticulum (ER) dysfunction might have an important part to play in a range of neurological disorders, including cerebral ischaemia, sleep apnoea, Alzheimer’s disease, multiple sclerosis, amyotrophic lateral sclerosis, the prion diseases, and familial encephalopathy with neuroserpin inclusion bodies.

What are facts about endoplasmic reticulum?

endoplasmic reticulum (ER) A system of membranes within the cytoplasm of plant and animal cells. It forms a link between the cell and nuclear membranes (see cisterna ) and is the site of protein synthesis.
