Calcium is primarily stored in the bones and teeth, where it is a key component of hydroxyapatite, providing structural support and strength. Additionally, small amounts of calcium are found in the bloodstream, where it plays critical roles in muscle contraction, nerve transmission, and blood clotting. Intracellularly, calcium is stored in the endoplasmic reticulum and mitochondria, which regulate its release for cellular signaling processes.
What else can I help you with?
When dietary intake of calcium is low calcium is removed from the bones?
The bones of your body are a storage place for calcium among other things. When you need calcium, the bones release it, when you don't, they take it up and store it once again.
What are the Skeletal muscle cells that function in calcium storage?
Sarcoplasmic reticulum is the type of skeletal muscle cell that functions in calcium storage. It plays a critical role in regulating intracellular calcium levels during muscle contraction and relaxation.
The binding of calcium to which molecule causes the myosin binding sites to be exposed?
Troponin binds to the Calcium ions to expose the actin to the myosin heads.
Which organelle is responsible for Ca storage in muscle cells?
The organelle responsible for calcium storage in muscle cells is the sarcoplasmic reticulum (SR). It plays a crucial role in muscle contraction by releasing calcium ions in response to signals from the nervous system. The SR helps regulate calcium levels, allowing for proper muscle function and contraction.
What areThe three major functions of the endoplasmic reticulum?
The endoplasmic reticulum (ER) plays a crucial role in protein synthesis, lipid metabolism, and calcium storage within cells. It is involved in folding and modifying proteins, synthesizing lipids, and regulating calcium levels in the cytoplasm.
Calcitonin acts in opposition to?
Parathyroid hormone opposes the effect of calcitonin, a hormone produced by the thyroid gland that regulates calcium levels. It removes calcium from its storage sites in bones and releases it into the bloodstream.
What is specialized for the storage and release of calcium?
The endoplasmic reticulum is specialized for the storage and release of calcium. This organelle has calcium pumps that actively transport calcium ions into its lumen for storage, and calcium channels that release calcium into the cytoplasm during cell signaling processes.
Where in the body are calcium and phosphorus stored before being released into the bloodstream?
Calcium and phosphorus are primarily stored in the bones and teeth. When needed, they can be released from these storage sites into the bloodstream to maintain their levels for various bodily functions.
What organ system is a storage place for calcium and phosphorus?
Calcium and phosphorus are two of the minerals found in the body. The skeletal system serves as a storage place for calcium and phosphorus.
What organ serves as a storage place for calcium and phosphorus?
skeletal
What system serves as a storage place for calcium and phosphorus?
skeletal
What are some available document storage software?
There are many online sites available for document storage. Google Drive, Dropbox, and Sugarsync are the most popular storage sites available for everyday use.
Where can one get storage servers?
One can get storage servers from multiple sites on the internet. Some of those sites are Wuala, Remote Storage, Rack Space, Tech Net, Amazon and ION Computer.
What organ system serves as a storage place for calcium and and phosphorus?
skeletal
Do Internet storage sites store applications?
of course you can，even some sites you can run program on it.
What do teeth do for the skeletal system?
Another calcium and other mineral storage place
After nervous stimulation of the muscle cell has ceased what happens to the calcium?
calcium is actively pumped into the extracellular fluid for storage until the next contraction
