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.
This network of sacs, the endoplasmic reticulum (ER), often makes up more than 10 percent of a cell's total volume. The endoplasmic reticulum comes in two types: Rough ER is covered with ribosomes and prepares newly made proteins; smooth ER specializes in making lipids and breaking down toxic molecules.Take a closer look, and you'll see that the sacs are covered with bumps about 2 inches wide.his network of sacs, the endoplasmic reticulum (ER), often makes up more than 10 percent of a cell's total volume.
