The smooth endoplasmic reticulum lacks ribosomes and functions in lipid manufacture and metabolism, the production of steroid hormones, and detoxification. I agree with pramod the smooth er performs a wide variety of functions, which makes it hard to come up with a solid analogy i would also caution against taking analogies about other organelles too seriously, as many organelles have additional roles beyond what simple analogies convey small . What does the endoplasmic reticulum do in a cell, its definition and role types of endoplasmic reticulum: rough and smooth know here. The smooth endoplasmic reticulum lacks ribosomes and functions in lipid manufacture and metabolism, the production of steroid hormones, and detoxification the smooth er is especially abundant in mammalian liver and gonad cells.
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 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. The smooth endoplasmic reticulum is a continuous section of the rough endoplasmic reticulum, it just has no or few ribosomes smoother sections of endoplasmic reticulum can also be found in the rough endoplasmic reticulum and they function as places the vesicles can leave the rough endoplasmic reticulum through, they are fittingly called . The rough endoplasmic reticulum, also called the rer, is involved with protein synthesis the rer works by producing proteins and helping them fold properly the rer gets its name from a series of studded ribosomes that produce proteins the ribosomes are located on the cytosolic side of the .
Smooth endoplasmic reticulum is also involved in the storage of calcium in muscle cells at the time of need, such as during muscle contraction, this stored calcium is released into the cytosol -- the liquid inside the muscle cells. The endoplasmic reticulum, or er, is an organelle found in all eukaryotic cells within each cell it is a widely distributed membrane structure that serves as the the site for modification of proteins, manufacture of macromolecules and lipids, and the transfers substances throughout the cell the er . Smooth endoplasmic reticulum function smooth er is like a factory inside of your cells, so its primary function is making stuff and breaking it down depending on the location of the cell, the .
The smooth endoplasmic reticulum in most cells is much less extensive than the rough endoplasmic reticulum and is sometimes alternatively termed transitional smooth endoplasmic reticulum is chiefly involved, however, with the production of lipids (fats), building blocks for carbohydrate metabolism, and the detoxification of drugs and poisons. The duties of the smooth endoplasmic reticulum vary depending on the type of cell, but one of the most important functions of this cellular structure is the synthesis of phospholipids and cholesterol the smooth endoplasmic reticulum carries out these duties in a variety of cells, but plays more . Rough endoplasmic reticulum contains ribosomes, while smooth endoplasmic reticulum does not contain ribosomes the ribosomes are what give rough endoplasmic reticulum its characteristic roughness .
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. 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). Smooth endoplasmic reticulum micrograph of rough endoplasmic reticulum network around the nucleus (shown in lower right-hand side of the picture) dark small circles in the network are mitochondria . The endoplasmic reticulum (er) is contiguous to the outer of the two nuclear membranes and forms a membranous network throughout the whole cell it is divided into two parts: the smooth (ser) and the rough endoplasmic reticulum (rer). Did you know that the smooth endoplasmic reticulum has a vital role in the detoxification process, that takes place in the liver it has been noted that the amount of smooth er in the liver increases considerably, when there is an overload of toxins in the body.
Structurally, the endoplasmic reticulum is a network of membranes found throughout the cell and connected to the nucleus the membranes are slightly different from cell to cell and a cell’s function determines the size and structure of the er. 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 smooth endoplasmic reticulum refers to regions on the endoplasmic reticulum where ribosomes are not attached these two regions of the endoplasmic reticulum are distinct from each other the lumen of the endoplasmic reticulum contains the newly synthesized soluble proteins that are to be secreted. The endoplasmic reticulum (er) is an organelle found in the cells of eukaryotic organisms it is an interconnected network of flattened sacs or tubes encased in membranes these membranes are continuous, joining with the outer membrane of the nuclear membrane er occurs in almost every type of .
The rough endoplasmic reticulum (rough er) is a a complex membrane-bound organelle and is involved in the transport of the proteins made by ribosomes on its surface found in eukaryotic cells — the cells of plants, animals, and humans. The smooth endoplasmic reticulum has functions in several metabolic processes, including synthesis of lipids, metabolism of carbohydrates and calcium concentration, drug detoxification, and . The endoplasmic reticulum (er) serves important functions particularly in the synthesis, folding, modification, and transport of proteinsdifferences in certain physical and functional characteristics distinguish the two types of er, known as rough er (rer) and smooth er (ser).
