NaSO4
30
What is the function of Sodium, Potassium, and Chlorine in the body
They act as electrolytes (e- charged, dissolved substances that maintain ionic balance and keep cells alive)
31

deficiency of iodine - hypothyroidism excess of iodine - hyperthyroidism
46
What is the function of molybdenum? What are the symptoms of toxicity?
molybdenum is an enzyme cofactor. toxicity inhibits copper absorption and can cause Cu deficiency
