- Photo by: Lemonade. The endoplasmic reticulum (ER) is a series of interconnected membranes or flattened sacs adjacent and connected to the nuclear membrane. The ER comes in two different morphological forms: smooth endoplasmic reticulum (sER) and rough endoplasmic reticulum (rER). The primary function of the sER is to serve as a platform for the synthesis of lipids (fats), carbohydrate (sugars) metabolism , and the detoxification of drugs and other toxins.

Histology Testbank: Cells 2a Endoplasmic reticulum is a system of tubules. If there are ribosomes on the tubules, it is termed rough endoplasmic reticulum. Ribosomes produce proteins. When the ribosomes are attached to endoplasmic reticulum, the proteins produced by the ribosomes are exported.

Endoplasmic reticulum 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.he surface of the rough endoplasmic reticulum (often abbreviated RER or Rough ER) (also called ergastoplasm) is studded with protein-manufacturing ribosomes giving it a rough appearance (hence its name).

The Endomembrane System and Proteins Describe the structure of the endoplasmic reticulum and its role in synthesis and metabolism. 1  If the endoplasmic reticulum (ER) has ribosomes attached to it, it is called rough ER; if it does not, then it is called smooth ER.  The proteins made by the rough endoplasmic reticulum are for use outside of the cell.

- ER stress and the UPR in mammals. The endoplasmic reticulum (ER) is a membranous network of branching tubules and flattened sacs that is present in all eukaryotic cells. It extends throughout the cytoplasm of the cell and is contiguous with the nuclear envelope.The ER is mainly recognized as a protein-folding factory, responsible for the biosynthesis, folding, assembly and modification of numerous soluble proteins and membrane proteins.t extends throughout the cytoplasm of the cell and is contiguous with the nuclear envelope.

In a cell what is the function of the endoplasmic reticulum? Two patterns are found in the cell, the smooth endoplasmic reticulum and the rough endoplasmic reticulum. The smooth endoplasmic reticulum packages proteins for transport, synthesizes membrane phosolipids, and releases calcium.echnical Answer: The endoplasmic reticulum has two parts to it. The Rough ER has many Ribosomes lining its inside and creates proteins for the cell which are either used or sent to the Golgi Apparatus for transportation.

Functions of the Rough and Smooth Endoplasmic Reticulum These secretory proteins are packaged into vesicles before being transported out of the rough endoplasmic reticulum. Membrane factory: The rough endoplasmic reticulum grows by adding phospholipids and membrane proteins to its own network. It assembles phospholipids with precursors in the cytosol.hese ribosomes are called membrane bound ribosomes and are attached to the cytosolic side of the endoplasmic reticulum. Ribosomes on the cytosolic side of the endoplasmic reticulum are responsible for the assembly of various proteins. The process of protein assembly is called translation.

Rough Endoplasmic Reticulum: Definition, Structure & Functions The endoplasmic reticulum is a membrane system of folded sacs and interconnected channels that serves as a site for protein and lipid synthesis. The various folds of the endoplasmic reticulum provide a large surface where cellular functions can take place. There are two types of endoplasmic reticulum: smooth and rough.

Endoplasmic reticulum The smooth endoplasmic reticulum (abbreviated SER) has functions in several metabolic processes. It synthesizes lipids, phospholipids, and steroids. Cells which secrete these products, such as those in the testes, ovaries, and sebaceous glands have an abundance of smooth endoplasmic reticulum.

Endomembrane system The surface of rough endoplasmic reticulum is covered with ribosomes, giving it a bumpy appearance when viewed through the microscope. This type of endoplasmic reticulum is involved mainly with the production and processing of proteins that will be exported, or secreted, from the cell. The ribosomes assemble amino acids into protein units, which are transported into the rough endoplasmic reticulum for further processing.

Lysosome Enzymes of the lysosomes are synthesised in the rough endoplasmic reticulum. The enzymes are released from Golgi apparatus in small vesicles which ultimately fuse with acidic vesicles called endosomes, thus becoming full lysosomes.

Endoplasmic Reticulum Examples of protein synthesis by the rough endoplasmic reticulum are the proteins produced in secretory cells. These include the digestive enzymes produced in the stomach and the protein hormones like insulin produced in the pancreas.he ribosomes on the rough endoplasmic reticulum manufacture proteins which enter the channels of the endoplasmic reticulum and move to places where they can create pockets.

Describe the Structure of the Endoplasmic Reticulum? Proteins for use within the eukaryotic cell or intended for organelles such as mitochondria, chloroplasts, and peroxisomes are synthesized by mRNA molecules attached to ribosomes in the cytoplasm.
