Endoplasmic Reticulum The endoplasmic reticulum is a multifold membranous structure within eukaryotic cells which plays a major role in the synthesis of the complex molecules required by the cell and the organism as a whole.rgan systems which produce many proteins have cells with a large amount of rough endoplasmic reticulum. The smooth endoplasmic reticulum plays a major role in synthesizing lipids by means of enzymes embedded in these smooth membranes.

Cell nucleus The Nuclear Envelope The nuclear envelope is a double-layered membrane that encloses the contents of the nucleus during most of the cell's lifecycle.The outer nuclear membrane is continuous with the membrane of the rough endoplasmic reticulum (ER), and like that structure, features numerous ribosomes attached to the surface.he other intermediate filament network is located on the outside of the outer nuclear membrane and is not organized in such a systemic way as the nuclear lamina. The amount of traffic that must pass through the nuclear envelope on a continuous basis in order for the eukaryotic cell to function properly is considerable.

What is the importance of the endoplasmic reticulum? It is ‘smooth’ because it is not studded with ribosomes and is associated with smooth slippery fats. CELLS NEED THE ROUGH AND THE SMOOTH. Think of a cell as a “multitude of membranes” we said in an earlier section. This statement certainly applies to the endoplasmic reticulum an organelle found in eukaryotic cells.About 50% of the total membrane surface in an animal cell is provided by endoplasmic reticulum (ER).ough ER (RER) is involved in some protein production, protein folding, quality control and despatch. It is called ‘rough’ because it is studded with ribosomes. Smooth E R (SER) is associated with the production and metabolism of fats and steroid hormones.

- It is the rough endoplasmic reticulum that is directly continuous with the nuclear envelope (as illustrated in Figure 1), which is also studded with ribosomes, and the two organelles are thought to have evolved simultaneously in ancient cells.

Endoplasmic Reticulum: Structure and Function The endoplasmic reticulum is a network of tubules and flattened sacs that serve a variety of functions in plant and animal cells. There are two regions of the ER that differ in both structure and function. One region is called rough ER because it has ribosomes attached to the cytoplasmic side of the membrane. The other region is called smooth ER because it lacks attached ribosomes. Typically, the smooth ER is a tubule network and the rough ER is a series of flattened sacs.

Endoplasmic reticulum and Protein Sorting What is the endoplasmic reticulum? The endoplasmic reticulum is a network of membrane-enclosed tubules and sacs, called cisternae. This network extends from the nuclear envelope throughout the cytoplasm (remember that the outer membrane of the nuclear envelope is continuous with the rough endoplasmic reticulum).here are two types of endoplasmic reticulum (ER) - smooth and rough. The rough kind is covered with ribosomes on its outer surface and is involved in protein processing and sorting.

When ribosomes are attached it is called rough ER and smooth ER when there are no ribosomes attached. The rough endoplasmic reticulum is where most protein synthesis occurs in the cell. The function of the smooth endoplasmic reticulum is to synthesize lipids in the cell.

- The endoplasmic reticulum manufactures, processes, and transports a wide variety of biochemical compounds for use inside and outside of the cell. Consequently, many of the proteins found in the cisternal space of the endoplasmic reticulum lumen are there only transiently as they pass on their way to other locations.ccordingly, the nucleus has direct access to proteins (many of which are produced by the ribosomes upon its surface) and other materials present in the endoplasmic reticulum lumen, so that transport vesicles are not needed to obtain them.
