calcium homo-states Flashcards
1
Q
Calcium homeostasis is regulated via
A
Interstinal calcium uptake
calcium absorption in the kidneys
bone calcium regulation
2
Q
As calcium homeostasis endocrine or exocrine control
A
endrocrine
3
Q
Calcium concentrations
A
Extracellular 1x10-3M
cytoplasmic 1x10-7M
ER/SR membrane 2-3X10-4M
4
Q
ATP -dependent mechanisms to set up calcium gradients and sell
A
Plasma membrane calcium ATP\ase, SERCA
5
Q
Mechanisms that increase calcium can involve moving across two different membranes name these
A
Plasma membrane or ER/SR
6
Q
Calcium movement across the plasma membrane
A
Voltage operated calcium channels
ligand gated ion channels
7
Q
Calcium movement out of the ER/SR
A
Calcium induced calcium release = RYANODINE receptor
