What chemical triggers sliding of muscle filaments?
The chemical that triggers the sliding of muscle filaments is calcium ions. When muscle cells receive a signal to contract, calcium ions are released into the muscle cell, binding to specific proteins and initiating the sliding mechanism between actin and myosin filaments in the muscle cells.
What endocrine glands manages the calcium level in blood stream?
The Parathyroid glands are situated on posterior side of thyroid gland. They are responsible for increasing the level of calcium ions in blood.
What ions are in calcium chloride?
Calcium chloride consists of calcium ions (Ca2+) and chloride ions (Cl-).
What is the gland that is responsible for producing a hormone that increases the level of calcium ions in the blood called?
The gland responsible for producing a hormone that increases the level of calcium ions in the blood is the parathyroid gland. The hormone produced is called parathyroid hormone (PTH), which helps regulate calcium levels in the body by increasing calcium absorption from the intestines and releasing it from bones.
How many calcium ions in one mole?
A mole of calcium has 6.022 X 1023 calcium ions.
A mineral that contains calcium carbonate will provide a positive response to a test for .?
acid reaction
When a muscle is relaxed the level of Ca ions in the cell is what?
When a muscle is relaxed, the level of calcium ions (Ca²⁺) in the muscle cell is low. This occurs because calcium ions are actively pumped back into the sarcoplasmic reticulum, reducing their concentration in the cytosol. As a result, the binding sites on actin for myosin are blocked by tropomyosin, preventing muscle contraction. Consequently, the muscle remains in a relaxed state until calcium is released again.
Do calcium ions react with sulphuric acid?
Yes, calcium ions (Ca2+) can react with sulfuric acid (H2SO4) to form calcium sulfate (CaSO4) and water (H2O). This is a double displacement reaction where the calcium ions in the calcium sulfate are derived from the calcium hydroxide that is formed after the initial reaction between calcium ions and sulfuric acid.
Formula for the compound formed by calcium ions and chloride?
Calcium chloride is the compound formed by calcium ions and chloride ions. Its chemical formula is CaCl2.
Is Calcium sulfate a base?
No, calcium sulfate is not a base. It is a salt composed of calcium ions and sulfate ions.
What ions are present in what ratio in a solution of aqueous calcium chloride?
In an aqueous solution of calcium chloride, the ions present are Ca²⁺ (calcium) and Cl⁻ (chloride) in a 1:2 ratio. This means for every calcium ion, there are two chloride ions present in the solution.
What are the ions for calcium fluoride?
The individual ions for calcium fluoride have the formulas Ca+2 and F-1 respectively. That means that in any sample of calcium fluoride, there must be twice as many of the fluoride ions.
