- bone calcium
Function of Parathyroid hormone in metabolism of calcium
Increases calcium reabsorption in kidney & decreases phosphate reabsorption
Function of Calbindin in metabolism of calcium
Intracellular protein that ferries calcium across the intestinal epithelial cells
Function of Calcitonin in metabolism of calcium
decreases calcium and phosphate reabsorption in kidney
Function of Vitamin D in metabolism of calcium
Increases intestinal absorption of calcium and phosphate
Calcium is pumped from the cytosol to ER lumen by
Calcium ATP-ases
Calcium is pumped out of the cell by
- sodium/ calcium exchangers
- calcium/ proton ATP- ases
How does Vitamin D defficiency occur?
- Vit. D defficiency results from a combination of inadequate exposure to sunlight and decreased dietary intake of Vit. D
- causes problem with bones in children - Rickets (bowed long bones) and in adults Osteomalacia (softening of bones)
