Calcium ions are actively imported from the cytoplasm into the Endoplasmic reticulum
Wiki User
∙ 11y ago
The increased concentration of Ca in the endoplasmic reticulum (ER) can be explained by the presence of specific Ca-ATPases pumps that actively transport Ca ions into the ER. These pumps work against the concentration gradient, using energy from ATP hydrolysis to pump Ca ions into the ER lumen, thereby increasing the concentration of Ca in the ER. This high calcium concentration in the ER is important for various cellular processes, such as protein folding and signaling.

Cause release of calcium in endoplasmic reticulum?
IP3. Inositol triphosphate. Cut from the membrane by something I can not remember ( a G protein action ) and then this lipid as part of this signal trasduction pathway docks on the ER and Ca(2+) is released to preform the cellular response.
What is ER in cells?
ER (endoplasmic reticulum) is a network of membranous tubes and sacs found in eukaryotic cells. It plays a key role in protein and lipid synthesis, as well as in processing and modifying newly synthesized proteins. There are two types of ER: rough ER, which has ribosomes on its surface and is involved in protein synthesis, and smooth ER, which lacks ribosomes and is involved in lipid metabolism and detoxification.
Cell stimulated to increase steroid production will have abundant?
mitochondria to support the increased metabolic activity required for steroid synthesis.
What is the difference between an animal cells er and plant cells er?
The endoplasmic reticulum (ER) in animal and plant cells have similar structures and functions. However, plant cells typically have a more extensive network of ER due to their larger size and need for increased protein synthesis to support cell wall production. Additionally, plant cells often contain specialized ER called the "smooth ER" that is involved in lipid metabolism and synthesis of molecules for cell wall construction.
What is the difference between the rough er and the smothe er?
Rough ER has Ribosomes and Smooth ER does not.
What explains the increased concentration of in the ER?
The endoplasmic reticulum (ER) contains a high concentration of Ca2+ ions due to the presence of specialized pumps (such as SERCA) that actively transport Ca2+ into the ER from the cytoplasm. This accumulation of Ca2+ within the ER is crucial for various cellular functions, including protein folding and lipid synthesis.
How do you break America into syllable?
Am-Er-I-Ca-
How many syllables are in carrier?
There are 3 syllables in the word carrier. Ca-rri-er.
How much smooth er is in a cell?
That depends on a cell. Since the smooth ER functions in detoxification and synthesis of lipid and carbohydrate, cells that are in livers will tend to have much more smooth ER concentration compared to a skin cell.
How many syllables in the word mail carrier?
"Mail carrier" has three syllables. It is pronounced as "mail" (1 syllable) and "car-ri-er" (2 syllables).

What cell part is made up of proteins and is responsible for moving things around in the cell?
The endoplasmic reticulum has two parts to it. The Rough ER has many Ribosomes lining its inside and creates proteins for the cell which are either used or sent to the Golgi Apparatus for transportation. Proteins that are created in the Rough ER have a higher chance of being secreted. The smooth ER's job is to remove toxins from the system, which is why a high concentration of Smooth ER is found in the liver.

Do ER doctors get paid by the amount of patients that are seen?
Perhaps it seems that ER physicians work on a "commission" basis because of the relatively short time they spend with their patients. These physicians are usually not on the payroll of the hospital, they are members of a "pool" of a private medical group who often rotate among several hospitals on a contract basis. As such, they are not reimbursed on a "per-patient" basis. They are paid by the number of hours they are staffed in that hospitals' ER. (This also explains why you often receive a separate bill from this ER group, in addition to one sent by the sponsoring hospital.)
