significance of OXYGEN part of water, used to make ATP
significance of CARBON forms bacbone chains, rings of all organic molecules: carbohydrates, lipids, protiens, nucleic acids
significance of HYDROGEN part of waterand most organic molecules, ionized form makes body fluids more acidic
significance of NITROGEN component of all protiens & nucleic acids
significance of CALCIUM makes bones and teeth harder, ionized form needed for blood clotting, release of some hormones, contraction of muscles, and other processes
significance of PHOSPHORUS component of nucleic acids, & ATP, needed for normal bone and tooth structure
significance of POTASSIUM ionized form is most plentiful cation in intracellular fluid, needed in making generating action potentials
significance of SULFUR component of some vitamins and many proteins
significance of SODIUM ionized form is most plentiful cation in extracellular fluid, needed for maintaining water balance to generate action potentials
significance of CHLORINE ionized form is most plentiful anion in extracellualr fluid, needed for maintaining water balance
significance of MAGNESIUM ionized needed for action of many enzymes
significance of IRON ionized forms are part of hemoglobin (in red blood cells) and some enzymes
POTASSIUM % total body mass 1.0
