What is smooth er function

This function of the smooth endoplasmic reticulum is so specialized in muscle cells that the organelle has a different name: the scarcoplasmic reticulum. Another specialized function of the smooth endoplasmic reticulum is its role in the gonads of animal species. Instead of releasing calcium ions, in these cells it assists in the last stages of steroid production.

A unique feature of this process is that smooth endoplasmic reticulum and mitochondria , another organelle, work together to produce steroids. This fact is exceptional as most organelles work as independent units when maintaining the cell's life functions. Certain genetic disorders interfere with the smooth endoplasmic reticulum. In cystic fibrosis , the body cannot properly create a certain protein.

This mutated protein becomes stuck in the smooth endoplasmic reticulum during packaging and is unable to leave the cell. Due to the absence of Ribosome on the Smooth Endoplasmic Reticulum, it appears smooth and while Ribosome is attached on the membrane of the rough Endoplasmic Reticulum, it appears rough.

The membranes of Smooth Endoplasmic Reticulum are highly curved and tubular, forming an interconnected system present in the cytoplasm and near to plasma membrane. According to some theories proposed by the scientists, the Smooth ER is an extension of the Rough ER which is itself an extension of the outer membrane of the nucleus.

After homogenization separation the Rough Endoplasmic Reticulum forms the fragments of rough vesicles while in case of Smooth ER smooth-surfaced vesicles are formed.

A protein called Reticulon is present in Smooth Endoplasmic Reticulum which is responsible for the curvature and bending of the Smooth ER. Smooth Endoplasmic Reticulum SER is mainly concerned with the synthesis of carbohydrate and lipids, and sometimes, with their metabolism. Crispiniano Zimmer Explainer. What is the endoplasmic reticulum made of? Endoplasmic reticulum is made up of a network of folded membranes much like the plasma membrane and is generally contiguous with the nuclear and plasma membrane.

Membranes are composed of a phospholipid bilayer with proteins embedded and are selectively permeable. Milca Enghardt Pundit. Why is the endoplasmic reticulum important? What is the function of the endoplasmic reticulum? The endoplasmic reticulum ER serves important functions particularly in the synthesis, folding, modification, and transport of proteins. Proteins synthesized by the RER have specific final destinations, such as the cell membrane, cell exterior, or the ER itself. Cecilia Fontsere Pundit.

What is the function of endoplasmic reticulum rough? The endoplasmic reticulum can either be smooth or rough , and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

Cherise Bethje Pundit. Who discovered the rough endoplasmic reticulum? Discovery of Endoplasmic Reticulum ER :. Otelo Belo Pundit. Where is smooth ER located? Enai Weidhase Pundit. Where is the smooth endoplasmic reticulum found? The smooth endoplasmic reticulum like the rough endoplasmic reticulum is connected to the nuclear envelope.

The smooth endoplasmic reticulum comprises tube-like structure located near the cell periphery. These tubules or tubes sometimes branch forming a network that is reticular in appearance. Rajan Cecchini Teacher. What would happen if there was no smooth endoplasmic reticulum? Without the RER the cell is not able to synthesis new plasma membrane proteins, lysosomal enzymes, proteines for the Golgi apparatus and proteins for extracellular secretion.

Because these kind of proteins are synthesised in the RER. In the absence of these cellular mechanisms the cell would probably die. Mira Roelofsen Teacher. Why do some ovaries have smooth ER?
