Calcium uses (6)
A
- Increases rigidity of bone, teeth and cartilage and is a component of the exoskeleton of crustaceans
- Important in clotting blood and muscle contraction
- Activator for several enzymes, such as ligase, ATPase and cholinesterase
- Stimulates muscle contraction and regulates transmission of nerve impulses
- Regulates permeability of cell membranes
- Important for cell wall development in plants, and formation of middle lamella between cell walls

Q
Sodium uses (4)
A
- Involved in regulation of osmotic pressure, control of water levels in body fluid and maintenance of pH
- Affects absorption of carbohydrate in the intestine, and water in the kidney
- Contributes to nervous transmission and muscle contraction
- Constituent of vacuole in plants which helps maintain turgidity
