I'll assume you mean in the extracellular space, and not inside the muscle cells. Acetylcholine is the neurotransmitter released from motor end-plates to trigger muscle contraction. So it anything BUT relaxes muscles. High levels of Ca ions on the other hand, make the muscle fibers unable to respond to stimuli, so effectively relax the muscle. (Intracellular Ca release causes contraction though!)
What else can I help you with?
Which ion is stored in the sarcoplasmic reticulum?
Calcium ions are stored in the sarcoplasmic reticulum of muscle cells. These ions play a crucial role in muscle contraction by triggering the release of more calcium ions into the muscle cell, leading to the contraction of the muscle fibers.
Does calcium carbonate increase specific conductivity of water?
Yes, calcium carbonate can increase the specific conductivity of water by adding more ions into the solution. When calcium carbonate dissolves in water, it forms calcium and carbonate ions, which can contribute to the overall conductivity of the water.
How can running affect your water balance ion balance and temperature?
ion- think it would affect it in a couple of ways: Muscles use ions to do work and therefore need a delicate balance of sodium, potassium and calcium in order to function well. Any type of prolonged exercise would disrupt this balance. More obviously, sweat contains lots of ions. So, the more you exercise the more ions you lose through sweat.
Why do muscles contract and relaxes rapidly?
When muscles contract and relax rapidly it is usually called twitching, or fasciculation. It is usually harmless and sometimes caused by a reflex action through the spinal cord, or from an imbalance in electrolytes in the blood, or even excess calcium inside the muscle cells. Rarely it is caused by a neurological problem. So unless it is constant and severe, it is more likely nothing to worry about.
Is calcium caltrate the same as calcium?
No the chloride ion is a chlorine atom that has gained an electron and has a -1 charge. Because it is charged the chloride ion must be accompanied by a positive ion of some sort to balance the charge. Calcium chloride is a compound that contains chloride ions (Cl-) and calcium ions (Ca2+) and has the formula CaCl2
What are all of the skeletal muscles in the body?
Muscles are set kind off like sets. Muscles can only contract and relax. It takes at least two muscles to move a part of the body fully. For example, when your arm is straight, your triceps (back of your arm) contract and the bicep relaxes. When your move your arm to a l shape, the bicep contacts and the tri relaxes. This happens through out the whole body.
Why one mole of calcium chloride would be more effective than one mole of sodium chloride?
One mole of calcium chloride would be more effective than one mole of sodium chloride because calcium chloride provides twice as many ions per formula unit, resulting in a higher concentration of ions in solution. This makes calcium chloride more effective in applications that require dissociation into ions, such as lowering the freezing point of water or enhancing road de-icing.
Why is sodium ions reduced to na while calcium does not in the electrolysis of fused nacl infact both ions are present in it. cacl2 to lower the melting point of na?
Sodium ions are reduced to form sodium metal because sodium has a lower reduction potential than calcium. This means it requires less energy to convert sodium ions into sodium metal compared to calcium ions into calcium metal. The presence of CaCl2 in the fused NaCl helps lower the melting point of NaCl, making the electrolysis process more efficient.
What are the goodness of calcium?
well it gives you brain power and is very good for your muscles and if you've got white patches on your nails it means that you need more calcium..
Are there beneficial substances that disslove in water?
yeah there are many disolved substances in water.some being calcium ions,fluoride ions,iron and many more which benefit us
Why does the ionic compound calcium fluoride have a different structure from that of calcium chloride?
Calcium fluoride has the fluorite structure where each calxium ion has 8 fluoride ions as near neighbours at the corners of a cube, and eacf fluoride has 4 calcium ions ate the corners of a tetrahedron. Another way of looking at this is that the calcium ions are close packed and the fluroide atoms fill the "tetrahedral holes" In calcium chloride the chloride ion is too large to allow eight coordination and the coordination around the calcium drops to 6, the coordination around the chloride has to drop to 3. This gives CaCl2 a unique structure which is a distorted form of the more regular rutile structure adopted by TiO2.
What effect changing the concentration of calcium ions has on the rate of coagulation of milk?
Rennin is an enzyme that converts the soluble milk protein caseinogen into the insoluble protein paracasein, producing the curd that can be processed into cheese or other milk products. Inorganic ions such as metal ions can act as cofactors. The ion may combine with either the enzyme or the substrate to reduce the activation energy. These ions are called activators. Activators are thought to make the enzyme substrate complex form more easily. For example, the action of amylase on starch is quicker in the presence of chloride ions. Calcium ions are required to activate the enzyme rennin. In this demonstration, calcium ion is removed by precipitating it as calcium citrate. In the tube containing the sodium citrate, calcium citrate forms as a precipitate. what effect changing the concentration of calcium ions has on the rate of coagulation of milk how calcium ions influece the activity of rennin in bringing about the coagulation of milk because it does
