Endoplasmic reticulum There are two types of endoplasmic reticulum, rough and smooth. The outer (cytosolic) face of the rough endoplasmic reticulum is studded with ribosomes that are the sites of protein synthesis.he 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.

Endoplasmic Reticulum Endoplasmic Reticulum. Endoplasmic reticulum is a continuous membrane, which is present in both plant cells, animal cells and absent in prokaryotic cells. It is the membrane of network tubules and flattened sacs, which serves a variety of functions within the cell.t can be defined as a eukaryotic organelle, which forms a network of tubules, vesicles and cisternae within the cells. There are two regions of the Endoplasmic reticulum, which differ in both structure and function.

Endoplasmic Reticulum 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.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.

- The endoplasmic reticulum is composed of sac-like structures called cisternae that are folded and bound together by a cytoskeleton. There are two types of endoplasmic reticulum: smooth endoplasmic reticulum and rough endoplasmic reticulum. Smooth endoplasmic reticulum gets its name from its smooth folded surface.ne of those organelles is the endoplasmic reticulum, which is an interconnected network of membrane vesicles, or small containers used by cells to transport or hold materials. The surface of the endoplasmic reticulum is basically a workspace for the cell.

Endoplasmic Reticulum: Structure and Function The endoplasmic reticulum is a network of tubules and flattened sacs that serve a variety of functions in the cell. 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. The space inside of the ER is called the lumen.

What is 'Endoplasmic Reticulum'? Endoplasmic reticulum is a network of tubules, vesicles and sacs that are interconnected. They may serve specialized functions in the cell including protein synthesis, sequestration of calcium, production of steroids, storage and production of glycogen, and insertion of membrane proteins.

What Is the Function of Endoplasmic Reticulum? Other examples of organelles include the nucleus, the mitochondria and the Golgi apparatus. The endoplasmic reticulum is one of the largest organelles in most cells and also plays a large role in maintaining the cell's shape. Two primary parts make up the endoplasmic reticulum: a cytoskeleton and numerous sac-like features called cisternae. There are two types of endoplasmic reticulum; one is called the smooth endoplasmic reticulum, while the other is called the rough endoplasmic reticulum.

Endoplasmic Reticulum FAQ There are two main types of endoplasmic reticulum - the rough endoplasmic reticulum and the smooth endoplasmic reticulum and both have different jobs to do. Other general functions of the endoplasmic reticulum include drug metabolism, storage of glycogen, facilitating the transport of proteins and protein folding.

Endoplasmic Reticulum - Wrapping it Up Another organelle in the cell is the endoplasmic reticulum (ER). While the function of the nucleus is to act as the cell brain, the ER functions as a manufacturing and packaging system. It works closely with the Golgi apparatus, ribososmes, mRNA, and tRNA. Structurally, the endoplasmic reticulum is a network of membranes found throughout the cell and connected to the nucleus. The membranes are slightly different from cell to cell and a cell’s function determines the size and structure of the ER.

Endoplasmic Reticulum: Structure and Function The endoplasmic reticulum is a network of tubules and flattened sacs that serve a variety of functions in the cell. 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.ince the ER is connected with the nuclear envelope, the lumen of the ER and the space inside the nuclear envelope are part of the same compartment. The rough endoplasmic reticulum manufactures membranes and secretory proteins. In certain leukocytes (white blood cells), the rough ER produces antibodies.
