What are the functions of 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. 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 the smooth endoplasmic reticulum for kids?
Smooth endoplasmic reticulum (SER). Among its functions is the production of proteins and steroids, the maintenance of plasma membranes, and a pathway for molecules to move along.
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 is a smooth ER simple definition?
Smooth endoplasmic reticulum (sER) is (a part of) endoplasmic reticulum that is tubular in form and lacks ribosomes. It is present in eukaryotic cells and is associated with lipid synthesis, carbohydrate metabolism, regulation of calcium concentration, and drug detoxification.
What do smooth and rough ER do?
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 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.
What is smooth endoplasmic reticulum kid definition?
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 …
