For Most Cells in the Body, the Intracellular Free [Ca²⁺]

Question

For most cells in the body, the intracellular free [Ca²⁺] is about A) 12 mM B) 1.2 mM C) 0.12 mM D) 10.2 µM E) Less than 1µ M

Accepted Answer

For most cells, the intracellular free calcium concentration is very low, typically less than 1 µM. This low concentration is maintained through various cellular mechanisms, including pumps and channels that regulate calcium influx and efflux.
