Smooth ER is more tubular than rough ER and forms a separate sealed interconnecting network. It is found fairly evenly distributed throughout the cytoplasm. It is not studded with ribosomes hence ‘smooth ER’.
Smooth ER is devoted almost exclusively to the manufacture of lipids and in some cases to the metabolism of them and associated products. In liver cells for example smooth ER enables glycogen that is stored as granules on the external (out side layer) surface of smooth ER to be broken down to glucose.
Smooth ER is also involved in the production of steroid hormones in the adrenal cortex and endocrine glands.
Smooth ER – the detox stop
Smooth ER also plays a large part in detoxifying a number of organic chemicals converting them to safer water-soluble products.
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 endeavor to detoxify overloads of ethanol derived from excess alcoholic drinking and also barbiturates from drug overdose.
To assist with this, smooth ER can double its surface area within a few days, returning to its normal size when the assault has subsided.The contraction of muscle cells is triggered by the orderly release of calcium ions.
These ions are released from the smooth endoplasmic reticulum inner surface.
The smooth endoplasmic reticulum (ER) is involved in lipid and steroid hormone synthesis, as well as detoxification of drugs and other harmful substances in the cell. It also plays a role in calcium ion storage.

Does the smooth endoplasmic reticulum have a single or double membrane?
yeh it is a double membrane bound organelle. the inner membrane is heavily folded for a large surface are for enzyme activity. its function is the synthesis, modification and distribution of protiens.
What contains a smooth outer and folded inner membrane in a cell?
The organelle that contains a smooth outer membrane and a folded inner membrane in a cell is the mitochondrion. Mitochondria are responsible for producing energy in the form of ATP through a process called cellular respiration.
Is the mitochondrion surrounded by a membrane?
Mitochondria have two [bi-lipid layer] membranes: a smooth and slightly elastic outer membrane and an inner membrane that has [surface area increasing] inward folds called cristae. Inside the inner compartment is the 'matrix', which is a gel-like phase that contains about 50% protein.
What is the function of the soft endoplasmic reticulum of a plant cell?
The function of the smooth endoplasmic reticulum in plant cells includes lipid metabolism, calcium storage, and detoxification of drugs and toxins. It lacks ribosomes on its surface and is involved in synthesizing lipids, including phospholipids and steroids.
What membrane is Rough ER connected to?
The rough endoplasmic reticulum (RER) is connected to the nuclear envelope, which is a double membrane surrounding the nucleus of a eukaryotic cell. Ribosomes attached to the RER play a crucial role in protein synthesis and modification.
What function is performed by smooth endoplasmic reticulum inside its membrane?
It makes lipids and carbohydrates.
What functions is performed by the smooth endoplasmic reticulum inside its membrane?
It makes lipids and carbohydrates.
Does the smooth endoplasmic reticulum have a single or double membrane?
yeh it is a double membrane bound organelle. the inner membrane is heavily folded for a large surface are for enzyme activity. its function is the synthesis, modification and distribution of protiens.
Smooth er makes membrane lipids called?
Smooth endoplasmic reticulum (SER) synthesizes membrane lipids, such as phospholipids and cholesterol, which are essential components of the cell membrane. These lipids are important for maintaining the structure and function of cell membranes and organelles.
Is basement membrane part of arteriole?
Yes. The arteriole has different layers of tissue from inside to out: endothelial layer, basement membrane, smooth muscle and then the extra cellular matrix. The basement membrane is composed of collagen and fibrillin.
Is the outer membrane of chloroplast rough or smooth?
it is smooth
What is the definition of endcardium?
The word endocardium means the thin, smooth membrane inside the hearts valves and chambers. It is composed of endothelial cells.
What is the smooth endoplastic reticulum's function?
It contains collections of enzymes that perform specialized tasks, including the synthesis of membrane lipids and the detoxification of drugs
What inside a cell?
The inside of a cell contains: nucleas,cytoplasm,golgi bodies, cell membrane, ilybosome,ribosome,valocule, smooth endoplasmic reticlum, rough endoplasmic reticulum, and of course DNA.
What is the role of an individual in the smooth function of BBMP?
What is the roll of an individual in the smooth function of bbmp
Is the smooth ER membrane bound?
Yes, the smooth endoplasmic reticulum (ER) is membrane-bound. It lacks ribosomes on its surface, giving it a smooth appearance compared to the rough ER, which has ribosomes attached. The smooth ER plays a role in lipid metabolism and detoxification processes within the cell.
How does rough er differ from smooth er structure and function?
ER (endoplasmic reticulae) are the pathways in the cytoplasm of the cell connecting the nucleus. Smooth ER are without ribosomes on its membrane and rough ER have several ribosomes lining up the membrane. The ribosomes help in the assembly of amenoacids to form the proteins as per message received from mRNA.
