STATE THE REGULATED SUBSTANCE OF CALCIUM | calcitonin, parathyroid hormone (PTH) and vitamin D. |
increases blood Ca2+ via bone resorption. | CALCITONIN |

blood Ca2+ via bone reabsorption. |
Second most abundant metal mineral of the human body with an approximate
mass of 230 grams. It is the major intracellular cation. | POTASSIUM |
STATE THE FUNCTIONS OF POTASSIUM | 1. Propagation of action potential in neural and muscular tissue.
2. Involved in fluid and electrolyte balance.
3. Acid-base homeostasis.
4. Glucose and insulin metabolism. |
Excess potassium is excreted in the urine with the influence of _ _ _ _ _ _ _ _ _ _ _ by exchanging potassium with sodium. | ALDOSTERONE |
Storage of potassium in the liver and muscles by _ _ _ _ _ _ _ | INSULIN |
in potassium is usually rare since cells can readily “pump”
out potassium. | DECREASE |
Second most abundant non-metal mineral in the body with an approximate mass
of 160 grams. | SULFUR |
STATE THE FUNCTION OF SULFUR | 1. Constitutes methionine, an essential amino acid.
2. Constitutes the B vitamins: biotin and thiamine.
3. Formation of disulfide bonds in protein assembly and structure.
4. Constitutes the reduced form of glutathione, a well-known antioxidant. |
The major extracellular anion. Has an approximate mass of 100 grams in the
human body. | CHLORIDE |
STATE THE FUNCTIONS OF CHLORIDE | 1. Regulation of osmotic pressure.
2. Regulation of electrolyte balance.
3. Involvement in acid-base homeostasis.
4. Role in transmitting action potential in neural and muscle tissues. |
In exchange with potassium, the hormone (what is the name of that hormone) promote reabsorption of
sodium along with chloride in cases of deficiency. | ALDOSTERONE |
excess in(WHAT MINERAL) usually
involves excess in (ANOTHER MINERAL) both passively excreted in the urine. | CHLORIDE AND SODIUM |
Major extracellular cation. Has an approximate mass of 100 grams in the human body. | SODIUM |
STATE THE FUNCTION OF SODIUM | 1. Regulates blood volume, and blood pressure.
2. Regulates osmotic equilibrium.
3. Involved in acid-base homeostasis. |
In exchange with potassium, the hormone promote reabsorption of sodium along with chloride in cases of deficiency. | ALDOSTERONE |
Since water levels is directly
proportional with sodium, the (WHAT HORMONE?) also promote sodium
retention. | anti-diuretic hormone |
Second most abundant intracellular cation with an approximate mass of 30 grams in the human body. | MAGNESIUM |
Interacts with phosphate in the formation of | DNA AND RNA |
STATE THE #2 FUNCTION OF MAGNESIUM | 2. Activator of enzymes that catalyzes ATP synthesis, and DNA synthesis. |
Regulated by the kidneys via reabsorption in cases of deficiency, and excretion in cases of excess. | MAGNESIUM |
STATE THE TRACE MINERALS | IRON, ZINC, COPPER, MANGANESE, IODINE, SELENIUM |
The most important trace element in the human body with an approximate mass of 2.6 grams. | IRON |
1. Constitutes oxygen-binding metalloproteins of muscle tissues (myoglobin) and
blood (hemoglobin).
2. Constitutes enzymes such as cytochrome and catalase. | FUNCTIONS OF IRON |
The human body conserves iron by recycling | heme proteins. (IRON) |
Iron can also be stored in the body in the form of ? | ferritin and hemosiderin |
WHAT DO YOU CALL THE TRANSPORT PROTEIN FOR IRON? | transferrin. |
Has an approximate mass of 2.2 grams in the human body. | ZINC |
STATE THE FUNCTIONS OF ZINC | Functions include:
1. Necessary for most enzyme functions that are involved in transcription.
2. Key factor in prostate gland function and reproductive organ growth.
3. Regulates apoptosis. |
major zinc homeostasis of the organ is
the (WHAT ORGAN?) mainly absorption from dietary sources. | INTESTINE |
Has an approximate mass of 100 mg in the human body. | COPPER |
STATE THE FUNCTION OF COPPER | 1. Involved in the electron transport chain.
2. Involved in anti-oxidative enzymes such as superoxide dismutase. |
Excess copper in the liver is excreted in? | BILE |
SPECIAL PROTEIN CALLED? IT IS KNOWN AS A CARRIER OF COPPER IN BLOOD | ceruloplasmin |
Copper is absorbed in the
intestines from dietary sources. Copper from bile is not reabsorbed by the
intestine. | ZINC (ADDITIONAL IDEA) |
Has an approximate mass of 20 mg in the human body. | MANGANESE, IODINE AND SELENIUM |
STATE ONE FUNCTION OF MANGANESE | Enzyme activator involved in macronutrient metabolism, bone formation, and
antioxidative functions. |
Stored primarily in the bones, but can also be stored in the liver and kidneys. | MANGANESE |
STATE ONE FUNCTION OF IODINE | 1. Synthesis of thyroxine and triiodothyronine. |
STATE THE TWO FUNCTION OF SELENIUM | 1. An activator of antioxidant enzymes such as glutathione peroxidases.
