The ER forms a network like structure in the cytoplasm that gives mechanical support to the cytoplasmic matrix. Be able to identify each of the organelles listed. It looks like your browser needs an update. The organelle is involved in the synthesis, folding, modification, and transport of proteins to different organelles within the cell or outside of the cell. It is responsible for the metabolism of carbohydrates. It is a subset of the endomembrane system of the endoplasmic reticulum. It is an interconnected network of flattened sacs or tubes encased in membranes. 3,serving as a transitional area for vesicles that transport endoplasmic reticulum products to various destinations. Take Exam 1,manufacturing membranes. It is also responsible for the synthesis of essential lipids such as phospholipids and cholesterol. The endoplasmic reticulum is a network of tubules and flattened sacs that serve a variety of functions in plant and animal cells. Polypeptides are synthesized, modified, folded into their correct 3-D shape and sorted towards an organelle or marked for secretion. The Endoplasmic Reticulum.

Function of smooth endoplasmic reticulum in liver. Endoplasmic reticulum performs the following functions: It is responsible for the production and secretion of steroid hormones. Endoplasmic Reticulum. These flattened, hollow folds and sacs are called cisternae. The endoplasmic reticulum serves many general functions, including the folding of protein molecules in sacs called cisternae and the transport of synthesized proteins in vesicles to the Golgi apparatus. Cell Theory . Endoplasmic reticulum is the interconnected system of membrane-bounded tubules and vesicles which form irregular reticulum or network in the cytoplasmic matrix. Here, the newly translated proteins get in contact with a dense meshwork of ER-resident proteins. It is found in eukaryotic plant and animal cells, and not in prokaryotic cells. Endoplasmic reticulum is a complex membrane lined network of flattened sacs, tubules and vesicles that runs throughout the cytoplasm of eukaryotic cells from plasma membrane to nuclear envelope. 10 Qs . The endoplasmic reticulum takes the proteins that are made by the ribosomes and folds them into sacs that are called cisternae.
