Calcium ions can bind to actin and promote actin polymerization, leading to the formation of actin filaments. This can regulate various cellular processes such as cell movement, muscle contraction, and cell signaling. Calcium ions can also affect the binding of other proteins to actin, influencing its function in the cell.
What else can I help you with?
Why temporary hardness is removed from water by boiling but permanent hardness is not?
Permanent hardness is hardness (mineral content) that cannot be removed by boiling. It is usually caused by the presence in the water of calcium and magnesium sulphates or chlorides which become more soluble as the temperature rises.
Acids give off what ions?
Acids give off H+ ions when dissolved in water. These H+ ions are responsible for the acidic properties of a solution.
What the result of heating calcium nitrate?
calcium nitrate decomposes upon heating to release nitrogen dioxide
What kind of chemical reaction is this CaCO3 - CaO CO2?
This is a decomposition reaction where calcium carbonate (CaCO3) breaks down into calcium oxide (CaO) and carbon dioxide (CO2) upon heating.
Show how each what strong electrolytes breaks up into its component ions upon dissolving in water NaBr?
When sodium bromide (NaBr) dissolves in water, it breaks up into Na+ and Br- ions. Na+ is the sodium cation and Br- is the bromide anion. These ions are then free to move independently in the solution, contributing to its conductivity.
Does the hardness of water depend upon the metal or non metal ion of the mineral?
The hardness of water depends primarily on the concentration and chemical identities of the metal cations dissolved in the water. The non metal ions dissolved in the water have little effect unless the particular ions are capable of forming coordinate covalent bonds to the metal ions.
What is the correct equation for the effect of heat on CacO3?
The correct equation for the effect of heat on CaCO3 (calcium carbonate) is: CaCO3 (s) -> CaO (s) + CO2 (g) This reaction represents the decomposition of calcium carbonate into calcium oxide and carbon dioxide upon heating.
Why temporary hardness is removed from water by boiling but permanent hardness is not?
Permanent hardness is hardness (mineral content) that cannot be removed by boiling. It is usually caused by the presence in the water of calcium and magnesium sulphates or chlorides which become more soluble as the temperature rises.
What has the author Bernice Lydia Kunerth written?

What is another name for the condition when the net force actin upon an object is zero?
balanced force
What acid mixed with calcium makes calcium sulphate?
Sulfuric acid will form calcium sulfate upon reaction with calcium.
The amount of neurotransmitter released at a synapse is controlled by?
The amount of calcium ions which come into the axon terminal after an action potential arrives, which depends in part upon the concentration of calcium ions inside and outside the neuron, and also upon the amplitude and shape of the arriving action potential (short duration AP spend less time above the Ca ion gate activation threshold, resulting in fewer gates being opened, therefore less Ca allowed in).
Is calcium sensitive to light?
Calcium itself is not sensitive to light. However, some calcium compounds or calcium-containing materials, such as calcium hypochlorite, can be sensitive to light and may degrade upon exposure.
How does coral make calcium carbonate?
The skeletons of dead corals are the foundation upon which layerer upon layer of successively younger animals attach themselves. The coral animal, or polyp, is colulmn shaped. Its lower end is attached to the hard floor made of the preceding coral skeletons of the reef, and its upper end extends into the water. There hard and soft corals, depending on the type of skeleton secreted. The hard-coral polyp deposits a cup-like solid skeleton of calcium carbonate around itself into which the polyp withdraws during the daytime. For this reason, deep sea divers see only the skeletons-and not the polyps-of hard corals.
What has the author William Curry Martin written?
William Curry Martin has written: 'The effect of cod liver oil and of butter fat upon the metabolism of calcium and phosphorous' -- subject- s -: Accessible book
Does calcium carbonate decompose to make calcium oxide and water?
Calcium oxide, or quicklime, can be decomposed chemically into its components, calcium and oxygen. Calcium is an element and cannot be decomposed chemically.
What is the shape of calcium chloride?
Calcium is a solid and it could be of any shape depending upon how we cut or break or grind calcium into pieces.
