Question | Answer |
---|---|
Ca 2+ | location: outside cell function: bone and tooth structure, blood clotting, muscle contraction and transmission of nerve impulses. |
Fe 2+ | location: blood hemoglobin function: transporting oxygen from lungs to cells. |
K + | location: fluid inside cells function: maintain ion concentrations in cells; regulates insulin release and heartbeat |
Na+ | location: fluid outside cells function: protect against fluid loss, necessary for muscle contraction and transmission of nerve impulses |
Mg 2+ | location: fluids inside cells, bone function: present in many enzymes, needed for energy generation and muscle contraction. |
Cl - | location: fluid outside cells, gastric juices function: maintain fluid balance in cells, helps transfer CO2 from blood to lungs |
HCO3 - | location: fluid outside cells function: control acid base balance in blood |
HPO4 2- | location: fluids inside cells, bone and teeth function: control acid base balance in cells. |
