• chemical symbol and role in biology of calcium?

  Ca2+

  involved in the transmittion of nerve impulses and the release of insulin from the pancreas. acts as a cofactor for many enzymes e.g. those involved in blood clotting. important for bone formation
• chemical symbol and role in biology of sodium?

  Na+

  generates nerve impulses, for muscle contraction and for regulating fluid balance in the body
• chemical symbol and role in biology of potassium?

  K+

  generating nerve impulses for muscle contraction and for regulating fluid balance in the body. activates essential enzymes needed for photosynthesis
• chemical symbol and role in biology of hydrogen?

  H+

  affects pH of substances. important for photosynthesis reactions
• chemical symbol and role in biology of ammonium?

  NH4+

  absorbed from the soil by plants and is an important source of nitrogen
