It has only one. Just like all normal endoplasmic reticulums. And other organelles. In a cell there are membranous organelles with two layer membranes (nucleus and mitochondria), membranous organelles with one layer membrane (lysosome, peroxisome, endoplasmic reticulum and Golgi complex) and organelles not surrounded by membranes (ribosome, nucleolus, centrosome, centriole and basal bodies). Even though the endoplasmic reticulum is continuous with the nuclear envelope (that contains a two layer membrane) it only contains one membrane because only the outer layer of the nuclear envelope is continouous with the ER.
What else can I help you with?
How many membranes surround the smooth endoplasmic?
The smooth endoplasmic reticulum is surrounded by a single membrane. It lacks ribosomes on its surface unlike the rough endoplasmic reticulum.
How many membranes does a endoplasmic reticulum have?
Any endoplasmic reticulum, smooth or rough, has one membrane. Just as there is one membrane around the nucleus, there is one around the ER. They appear to have many but they look this way because of how they are folded or formed. The Rough ER (RER) looks more like several pockets while the Smooth ER (SER) looks more like a bunch of tubes.
What is the function of Rough endoplasmic reticulum in animal cell?
The rough endoplasmic reticulum in animal cells is involved in protein synthesis. It has ribosomes attached to its surface which help in the translation of mRNA into proteins. These proteins are then modified and transported to other parts of the cell.
Endoplasmic reticulum where proteins are built?
The endoplasmic reticulum is an organelle in the cell where proteins are synthesized, folded, and modified. It plays a crucial role in protein production and quality control before they are transported to their final destinations within or outside the cell. There are two types of endoplasmic reticulum: rough endoplasmic reticulum (with ribosomes attached) and smooth endoplasmic reticulum (without ribosomes).
What form parts of cell membranes and many of the cell's organelles?
The answer is proteins.
How many membranes surround the smooth endoplasmic?
The smooth endoplasmic reticulum is surrounded by a single membrane. It lacks ribosomes on its surface unlike the rough endoplasmic reticulum.
Is it true that Many membrane proteins are made by the smooth endoplasmic reticulum?
No, membrane proteins are usually synthesized by ribosomes on the rough endoplasmic reticulum (ER) and then undergo processing and modifications in the ER and Golgi apparatus before being incorporated into cellular membranes. The smooth ER is primarily involved in lipid metabolism and detoxification reactions.
How many are endoplasmic reticulum?
There are two types of endoplasmic reticulum, rough ER and smooth ER. Rough ER is studded with ribosomes and is involved in protein synthesis, whereas smooth ER is involved in lipid synthesis and detoxification.
What are the hallways of the cell?
ENDOPLASMIC RETICULUM (ER) Endoplasmic Reticulum The endoplasmic reticulum is a network of membranes found within almost all eukaryotic cells. The membranes are connected to the membrane of the cell’s nucleus and are important for many cellular processes such as protein production and the metabolism of lipids and carbohydrates. The endoplasmic reticulum includes both the smooth ER and the rough ER. The smooth ER is a smooth membrane and has no ribosomes, whereas the rough ER has ribosomes that are used to produce proteins.
Which is an organelle found in the cytoplasm has a smooth outer membrane and greatly folded inner membrane?
Endoplasmic Reticulum: a series of highly folded membranes, "rough" endoplasmic reticulum has many ribosomes attached to it. "Smooth" endoplasmic reticulum has no ribosomes attached to it and is the structure where fats (lipids) are made but both types of endoplasmic reticulum carry materials through the cytoplasm.
Many membrane proteins are made by the Smooth endoplasmic reticulum true or false?
true

What is the of the endoplasmic reticulum?
here are several definitions i found on dictionary.comDictionary.com Unabridged (v 1.1) - Cite This Source - Share Thisendoplasmic reticulum-noun Cell Biology. a network of tubular membranes within the cytoplasm of the cell, occurring either with a smooth surface (smooth endoplasmic reticulum) or studded with ribosomes (rough endoplasmic reticulum), involved in the transport of materials.American Heritage Dictionary - Cite This Source - Share This endoplasmic reticulumn. A membrane network within the cytoplasm of cells involved in the synthesis, modification, and transport of cellular materials.endoplasmic reticulum (ěn'də-plāz'mĭk) Pronunciation KeyAn organelle consisting of a network of membranes within the cytoplasm of eukaryotic cells that is important in protein synthesis and folding and is involved in the transport of cellular materials. The endoplasmic reticulum can be continuous in places with the membrane of the cell nucleus. The function of the endoplasmic reticulum can vary greatly with cell type, and even within the same cell it can have different functions depending on whether it is rough or smooth. ◇ The rough endoplasmic reticulum is a series of connected flattened sacs that have many ribosomes on their outer surface. Rough endoplasmic reticulum synthesizes and secretes serum proteins (such as albumin) in the liver, and hormones (such as insulin) and other substances (such as milk) in the glands. ◇ The smooth endoplasmic reticulum is tubular in form and is involved in the synthesis of phospholipids, the main lipids in cell membranes. Smooth endoplasmic reticulum is the site of the breakdown of toxins and carcinogens in the liver, the conversion of cholesterol into steroids in the gonads and adrenal glands, and the release of calcium ions in the muscles, causing muscle contraction. The smooth endoplasmic reticulum also transports the products of the rough endoplasmic reticulum to other cell parts, notably the Golgi apparatus. See more at cell.my knowlage: an organelle found inside of some cells often abbreaviated as ER. A rough ER is an ER with ribosomes stuck to it, and a smooth ER is one without ribosomes. the ER is often found around the nucleus. it can sometimes be confused with the Golgi complex because of their similar looking shape.this is alot of info!!!!!hope it helps!!!!!!
What form parts of cell membranes and many of the cell's organelles?
The answer is proteins.
What two organelles produces lipids?
The endoplasmic reticulum (smooth ER) and the golgi apparatus are organelles responsible for producing lipids in cells. The smooth ER is involved in lipid synthesis, while the golgi apparatus modifies and packages lipids for distribution within the cell or for secretion.
