Smooth ER: Definition, Functions & Structure Definition of the Smooth ER. 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.esson Summary. Smooth endoplasmic reticulum is a cellular organelle made up of a tube-like structure that folds over on itself many times. An organelle is a sub-unit within a cell that has a specialized function. It is responsible for making products and undergoing processes that the cell needs to function.

Endoplasmic reticulum The rough endoplasmic reticulum is especially prominent in cells such as hepatocytes. The smooth endoplasmic reticulum lacks ribosomes and functions in lipid metabolism, carbohydrate metabolism, and detoxification of drugs.The smooth ER is especially abundant in mammalian liver and gonad cells. The lacy membranes of the endoplasmic reticulum were first seen in 1945 using electron microscopy.n some cells, there are dilated areas like the sacs of rough endoplasmic reticulum. The network of smooth endoplasmic reticulum allows for an increased surface area to be devoted to the action or storage of key enzymes and the products of these enzymes.

The Endomembrane System and Proteins The smooth endoplasmic reticulum (SER) is continuous with the RER but has few or no ribosomes on its cytoplasmic surface. Functions of the SER include synthesis of carbohydrates, lipids, and steroid hormones; detoxification of medications and poisons; and storage of calcium ions.

The Structure & Function of the Rough and Smooth Endoplasmic Reticulum Transcript of The Structure & Function of the Rough and Smooth Endoplasmic Reticulum. If a polypeptide is translocated into the ER from a membrane bound ribosome it is known as co-translational translocation [3].he ER is a system of branching tubules and flattened sacs which extend throughout the cytosol [2]. It is continuous with the outer nuclear membrane [2,5,12]. The endoplasmic reticulum is the largest organelle in a eukaryotic cell [3].

Rough Endoplasmic Reticulum: Definition, Structure & Functions Rough endoplasmic reticulum is a form of endoplasmic reticulum that is studded with ribosomes. Since it has ribosomes stuck all over it, it has a bumpy appearance and is therefore called rough endoplasmic reticulum. Structure of Rough Endoplasmic Reticulum. Structurally, the rough endoplasmic reticulum looks like a pile of folded paper.

Legal Information The statement is to be followed if the individual is unable to provide instructions at the time medical decisions need to be made. The health care proxy is significantly different from the living will in that it empowers another person (the agent) to make health care decisions if the patient cannot do so herself. The living will, on the other hand, has no such provision but enables a person to express her own choices regarding medical treatment.

Information About the Smooth Endoplasmic Reticulum and Its Functions Proportion: The proportion of smooth endoplasmic reticulum is very small, when compared to that of rough ER. Smooth ER is mostly found in cells that are actively involved in synthesis and metabolism of lipids. It is prominently seen in the liver, ovaries, testes, muscles, etc.In short, smooth endoplasmic reticulum is primarily meant for storage and transport of lipids and proteins.roportion: The proportion of smooth endoplasmic reticulum is very small, when compared to that of rough ER.
