There are two distinct, though connected, regions of ER that differ in structure and function: smooth ER and rough ER. The rough endoplasmic reticulum is so named because the cytoplasmic surface is covered with ribosomes, giving it a bumpy appearance when viewed through an electron microscope. The smooth ER appears smooth since its cytoplasmic ...
The endoplasmic reticulum (ER) is a part of a 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).

translation and folding of new proteins (rough endoplasmic reticulum), expression of lipids (smooth endoplasmic reticulum) single-membrane compartment: all eukaryotes: rough endoplasmic reticulum is covered with ribosomes (which are bound to the ribosome membrane), has folds that are flat sacs; smooth endoplasmic reticulum has folds that are ...
Changed the smooth endoplasmic reticulum to look as a part of the rough ER. made ribosome smaller and more atached to the rough endoplasmic reticulum; made small membrane vesicles smaller and yellow. changed golgi vesicles to golgi body and aded the actual golgi vesicles. gruped elements that belonged together. made the file an SVG; English a.
The functionality of these proteins is based on their specific molecular design and interaction patterns. [8] Although reticulons do not share any primary sequence homology with DP1/Yop1p proteins, both families have a conserved domain of approximately 200 amino acids containing two hydrophobic segments (longer than conventional α-helical transmembrane domains).
Rough (containing ribosomes) and smooth (without ribosomes) microsomes are made from the endoplasmic reticulum through cell disruption. These microsomes have an inside that is exactly the same as the endoplasmic reticulum lumen. Both forms of microsomes can be purified by a process known as equilibrium density centrifugation. Rough and smooth ...
[3] [4] MCS are important in the function of the endoplasmic reticulum (ER), [5] since this is the major site of lipid synthesis within cells. [6] The ER makes close contact with many organelles, including mitochondria, Golgi, endosomes, lysosomes, peroxisomes, chloroplasts and the plasma membrane. [7]
