which structures are involved in regulating calcium levels?

Question

I would like to know what structures are involved or somewhere I can look to find the answer.

Answer 1

On a cellular level, the cell membrane contains special proteins called calcium channels that help maintain homeostasis of calcium levels in/out of the cell.
On the level of the body, the kidneys are responsible for regulating levels of nutrients such as calcium. A diverse set of gradients ensure that the levels of calcium in the body are maintained as this is very important for muscle contraction as well as a host of other metabolic processes. If this balance is altered, it results in conditions such as hypercalcemia (an excess of Ca) or hypocalcemia (a deficiency of Ca) which are both harmful to the body

Answer 2

At the cellular level, there are lots. The plasma membrane can remove calcium. The ER ((or SR in muscle) sequesters alot. So do mitochondria and probably peroxisomes as well. I chloroplasts, the chloroplasts and central vacuole alos take up calcium

Answer 3

generally there are some hormone do it in blood level (e.g serotonin)

at molecular level :Search "SERCA" on google or wikipedia.it is a P-class of ATPase which is in ER membrane.it mostly contribute to regulation of Ca levels in cells!however there are some Ca Chanels in Plasma membrane!
