How many membranes does a smooth endoplasmic reticulum have?
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.
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.
How many Smooth Endoplasmic Retciulums would you find in a cell?
One.
What form parts of cell membranes and many of the cell's organelles?
The answer is proteins.
Do red blood cells have smooth ER?
No, red blood cells do not have smooth endoplasmic reticulum. Red blood cells lack most organelles, including the endoplasmic reticulum, because their primary function is to carry oxygen throughout the body.
How many membranes surround the chloroplast?
10. -rund
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 endoplasmic reticulums are in a body?
There are two types.Rough and smooth endoplasmic reticulmn.
How many membranes surround the brain?
one its called meninges

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.
How many membranes surround bacteria?
Only 1 membrane surrounds bacterias

How many Smooth Endoplasmic Retciulums would you find in a cell?
One.
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.
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.
Many membrane proteins are made by the Smooth endoplasmic reticulum true or false?
true
