Is the rough endoplasmic reticulum responsible for calcium storage and release?

Yes.
"Smooth ER also is involved in the uptake and release of calcium to mediate some types of cellular activity. In skeletal muscle cells, for example, the release of calcium from the smooth ER triggers muscle contraction." Source: http://encarta.msn.com/encyclopedia_761587444/Endoplasmic_Reticulum.html

∙ 12y agoI had a test question tha aske "calcium ions are stored in..."
a. rough er
b. both rough and smoot er
c. cytoplasm
d. smooth er
I got it wrong but it is not B

∙ 11y agoNo , It is smooth endoplasmic reticulum but in muscle cells only .

An inhibitor of what could be used to block the release of calcium from the endoplasmic reticulum?
phospholipase C
What does the endoplasmic reticulum do in plant cell?
The smooth endoplasmic reticulum is a vast network of membrane-bound vesicles and tubules. It does the following: 1. lipid and steroid hormone synthesis 2. breakdown of lipid-soluble toxins in liver cells 3. control of calcium release in muscle cell contraction
What does a smooth endoplasmic reticulum do?
transports proteins to be used in the cell membrane. No ..... that's not true. It depends on what type of cell it is that the Smooth ER is in.
If a drug caused a sudden release of large amounts of calcium in skeletal muscle from which structure would the calcium come?
sarcoplasmic reticulum
What does the Golgi apparatus do in an animal cell?
Receive proteins and lipids form the endoplasmic reticulum. Labels the molecule made in the endoplasmic reticulum with a tack that specify their destination. Release molecule in vesicles
What is specialized for the storage and release of calcium?
smooth endoplasmic reticulum
An inhibitor of what could be used to block the release of calcium from the endoplasmic reticulum?
phospholipase C
Which organelles are responsible for the release of destructive enzymes in alzheimers?
Most likely the mitochondria (with respect to oxidative stress and apoptosis) and the endoplasmic reticulum.

What specific event initiates the contraction?
Calcium release from the sarcoplasmic reticulum initiates the contraction.

sarcoplasmic reticulum
How do cells release and produce proteins?
Amino acids are run along the ribosomes in the endoplasmic reticulum, they get instructions as to what chains to make from the nucleus.
What is the normal path way a cell uses to make and release proteins?
Ribosomes to Golgi Appartus(Body) to Endoplasmic Reticulum
Which organelles might you see in large quantities in cells that actively release proteins outside the cell?
ribsomes,golgi bodies,and endoplasmic reticulum
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!!!!!!
