Is calcium made up of cells?

Well honestly almost every living things contains cells but in this case yes calcium is made up of cells.

Explanation:

Calcium ions are either pumped out of the cell by a specific plasma membrane, Ca2+-ATPase (PMCA), or back into the sarcoplasmic reticulum by SERCA. The PMCA are encoded by at least four genes, PMCA1 and 4 are the most widely expressed and are the two isoforms expressed in vascular smooth muscle cells.

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics
