Smooth endoplasmic reticulum
Endoplasmic reticulum has two types, rough endoplasmic reticulum (rer) and smooth endoplasmic reticulum (ser) rough er is studded with ribosomes, the site of protein synthesis this type of er is especially prominent in certain kinds of cells like hepatocytes where active protein synthesis occurs. The smooth endoplasmic reticulum like the rough endoplasmic reticulum is connected to the nuclear envelope the smooth endoplasmic reticulum comprises tube-like structure located near the cell periphery these tubules or tubes sometimes branch forming a network that is reticular in appearance. Anatomical diagram with smooth and rough endoplasmic reticulum closeup with cisternae, nucleus, ribosomes, nuclear envelope pore and anatomical structure internal structure of an animal cell. The endoplasmic reticulum is a network of sacs that manufactures, processes, and transports chemical compounds for use inside and outside of the cell it is connected to the double-layered nuclear envelope, providing a pipeline between the nucleus and the cytoplasm.
Structure the typical hepatocyte is cubical with sides of 20-30 µm, (in comparison, a human hair has a diameter of 17 to 180 µm) the typical volume of a hepatocyte is 34 x 10 −9 cm 3 smooth endoplasmic reticulum is abundant in hepatocytes, whereas most cells in the body have only small amounts. What is the smooth endoplasmic reticulum made of & it’s definition the absence of the ribosomes on the structures confers the name smooth to the endoplasmic reticulum as such the cell types which are essentially involved in lipids production are rich in smooth endoplasmic reticulum. Endoplasmic reticulum (er) is a complex network of membranes, that is found in the form tubules, and compressed, sac-like structures called cisternae. The rough endoplasmic reticulum (rough er) is a part of the endomembrane system of the cell and a subset of the endoplasmic reticulum (er) this organelle is primarily concerned with the synthesis, folding and modification of proteins, especially those that need to be delivered to different organelles within the cell, or secreted from the cell.
Smooth endoplasmic reticulum in contrast to the rer, smooth endoplasmic reticulum lacks ribosomes and is not involved in protein synthesis note that the lack of ribosomes means that the smooth er is not basophilic and usually stains poorly by h&e. The smooth endoplasmic reticulum is more prominent in some cells than in others, depending on cell function  one cell type that contains a large quantity of smooth er is the hepatocyte found in the liver, these cells are heavily involved in processes that take place in the smooth er so need an expanded er to accommodate more enzymes [2. An analogy for smooth endoplasmic reticulum are the halls of a factory through which information passes the information in the case of a cell is messenger rna a cell is analogous to a factory raw materials go into the cell or a factory to produce goods, and the goods depend on the type of cell for instance, a cell in the pancreas produces. The endoplasmic reticulum is a network of tubules and flattened sacs that serve a variety of functions in plant and animal cellsthere are two regions of the er that differ in both structure and function. 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 so this is the function of endoplasmic reticulum.
The smooth endoplasmic reticulum or ser is no different when it comes to structure of endoplasmic reticulum yes, it is also a network of cisternae, vesicles and tubules 17 there are however a couple of differences between the structure of ser and rer the ser does not have ribosomes attached to its external surface. Endoplasmic reticulum - wrapping it up another organelle in the cell is the endoplasmic reticulum (er) while the function of the nucleus is to act as the cell brain, the er functions as a manufacturing and packaging system. The endoplasmic reticulum (er) is an organelle made up of a network of flattened sacs or tubules the membranes of the er are connected to the nuclear membrane and run through the cytoplasm there are two types of er: (1) the rough endoplasmic reticulum (rer) and (2) the smooth endoplasmic reticulum (ser. Endoplasmic reticulum and golgi bodies about transcript structure of the endoplasmic reticulum and golgi body (golgi apparatus) their role in protein secretion and then there's another region, which is the smooth endoplasmic reticulum and the role that this plays in protein synthesis, or at least getting proteins ready for the outside.
Smooth endoplasmic reticulum
The name smooth walled is given to that portion of endoplasmic reticulum that is devoid of ribosomes, like the rough walled endoplasmic reticulum smooth form shows a characteristic morphology which is tubular rather than cisternae. 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 similar to the er is the sarcoplasmic reticulum ( sr ) found only in muscle cells. Smooth endoplasmic reticulum is the site of the breakdown of toxins and carcinogens in the liver, the conversion of cholesterol into steroids in the gonads and adrenal glands, and the release of calcium ions in the muscles, causing muscle contraction the smooth endoplasmic reticulum also transports the products of the rough endoplasmic.
- Smooth endoplasmic reticulum vs rough endoplasmic reticulum endoplasmic reticulum, or er, is considered to be an organelle that composes the parts of the cell the cell is the functional unit of every body it may be the smallest unit, but it’s the structure that every organ in the body consists of, and without it systems in the body won.
- The endoplasmic reticulum is a highly versatile organelle involved in synthesis and transport of proteins, glycoproteins, and lipoproteins synthesis of cholesterol, steroids, phospholipids, and triglycerides it participates in degradation of glycogen, and in the metabolism of xenobiotics.
- The smooth endoplasmic reticulum has functions in several metabolic processes, including synthesis of lipids, metabolism of carbohydrates and calcium concentration, drug detoxification, and attachment of receptors on cell membrane proteins.
Smooth endoplasmic reticulum synonyms, smooth endoplasmic reticulum pronunciation, smooth endoplasmic reticulum translation, english dictionary definition of smooth endoplasmic reticulum adj smooth r , smooth st 1 a having a surface free from irregularities, roughness, or projections even see synonyms at level. Regions of er that lack bound ribosomes are called smooth endoplasmic reticulum, or smooth er in the great majority of cells, such regions are scanty and are often partly smooth and partly rough in the great majority of cells, such regions are scanty and are often partly smooth and partly rough. Endoplasmic reticulum an ultramicroscopic organelle of nearly all higher plant and animal cells, consisting of a system of membrane-bound cavities in the cytoplasm, occurring in two types: granular or rough-surfaced, bearing large numbers of ribosomes on its outer surface, and agranular or smooth-surfaced. The endoplasmic reticulum (er) is a network of membrane-enclosed tubules and sacs (cisternae) that extends from the nuclear membrane throughout the cytoplasm (figure 91) the entire endoplasmic reticulum is enclosed by a continuous membrane and is the largest organelle of most eukaryotic cells.
