The endoplasmic reticulum ( ER) is, in essence, the transportation system of the eukaryotic cell, and has many other important functions such as protein folding. It is a type of organelle made up of two subunits - rough endoplasmic reticulum ( RER ), and smooth endoplasmic reticulum ( SER ). All eucaryotic cells have an endoplasmic reticulum (ER). Its membrane typically constitutes more than half of the total membrane of an average animal cell (see Table 12-2). The ER is organized into a netlike labyrinth of branching tubules and flattened sacs extending throughout the cytosol (Figure 12-35). The endoplasmic reticulum ( ER) plays a key role in the modification of proteins and the synthesis of lipids. It consists of a network of membranous tubules and flattened sacs. The discs and tubules of the ER are hollow, and the space inside is called the lumen. Rough ER

7 years ago. The Endoplasmic Reticulum in a eukaryotic cell is the transport network of the cell and it extends from and connects the nuclear membrane to the plasma membrane of a cell. But then whenever we draw a diagram of a typical plant or animal cell, we never extend it to the plasma membrane- we always leave it somewhere in the cytoplasm. Fairly early on a certain sequence in the RNA may be recognised which causes the whole translation process to halt while the mRNA-ribosome complex is all transferred to the endoplasmic reticulum, translation will then begin again with the growing polypeptide chain entering the ER lumen. The process is known as cotranslational localisation. The endoplasmic reticulum, an organelle budding off the cell nucleus, plays a crucial role in protein synthesis and lipid metabolism. It's divided into two parts: the ribosome-studded rough endoplasmic reticulum, where protein synthesis occurs, and the smooth endoplasmic reticulum, responsible for lipid synthesis and detoxification. The Endoplasmic Reticulum. The endoplasmic reticulum (ER) is a series of interconnected membranous sacs and tubules that collectively modifies proteins and synthesizes lipids. However, these two functions are performed in separate areas of the ER: the rough ER and the smooth ER. The hollow portion of the ER tubules is called the lumen or.
Endoplasmic Reticulum Drawing
Introduction The endoplasmic reticulum (ER) is a structure found within the cytoplasm of eukaryotic cells. Its composition has two components: the smooth endoplasmic reticulum (SER) and the rough endoplasmic reticulum (RER). The endoplasmic reticulum (ER) is a large organelle made of membranous sheets and tubules that begin near the nucleus and extend across the cell. The endoplasmic reticulum creates, packages, and secretes many of the products created by a cell. Ribosomes, which create proteins, line a portion of the endoplasmic reticulum.
