Where is calcium released from in a muscle contraction? When the muscle is stimulated, calcium ions are released from its store inside the sarcoplasmic reticulum, into the sarcoplasm (muscle ). Invaginations of the plasma membrane (sarcolemma) of the muscle fibres are called T (or transverse) tubules.
How do you get rid of calcium deposits in your shoulder?

Why does calcium float in water class 10?
The reaction of calcium and water is less violent, the heat released is less. As the reaction proceeds, bubbles of H2 (g) and a white precipitate of Ca(OH)2are formed. The bubbles formed stick to the surface of calcium metal and make it lighter. Therefore, Calcium floats on water.

How acetone is prepared from calcium acetate?
Acetone can be prepared using calcium salt of acetic acid – calcium acetate. However during the reaction a lot of other chemical impurities are also produced. Calcium acetate when heated at a temperature of about 380° C decomposes, giving acetone and a residue of calcium carbonate.
