What is the Difference between Rough Er and Smooth Er
Cells are the basic building blocks of life. The complex structures of the cells have made their functioning complex. There are two types of components found in cells along with other many. These are rough Endoplasmic Reticulum and smooth Endoplasmic Reticulum. The eukaryotic cells contain these two components. The both reticulum can interchange and become the other based on the basic factor that any one of them can undergo any complex change due to the proteins in the membranes. What they are and what differences they contain in their nature is given below:
Rough ER
The rough ER is embedded with the proteins manufacturing ribosomes. This gives it a rough look this is the reason it is called rough ER. The ribosome are not, however, are the stable part of the organelle’s because the membrane of the eukaryotic cells constantly releases and bounds the proteins. The ribosome binds to the rough ER only when the protein begins to synthesize for secretary pathway from cell.
Smooth ER
Endoplasmic reticulum also called smooth ER lacks ribosome on its surface and is smooth in appearance. It involves the metabolism of certain compounds and synthesis of lipids. It is a network of tunnels extending from the nucleus to the Golgi bodies in the cell it is also a vacuole which contains digestive enzymes. Its structure is used for cell movement.
Rough ER vs Smooth ER
Smooth ER is not associated with ribosome while the rough ER is associated with the ribosome. The smooth ER is composed of tubules while rough ER is composed of cisternae. The smooth ER is associated with the plasma membrane while the rough ER is associated with the nuclear membrane. Smooth ER’s main function is lipid synthesis and hence it is mostly seen in cells associated with synthesis of steroid hormones while the main function of the rough ER is protein synthesis and hence mostly seen in cells associated with secretion of proteins.
