QuestionAnswer
Inorganic substances that are needed in small amounts compared to vitamins, which are also obtained via dietary intake.MINERALS
Needed in large quantities. Amounts ranging from 30 grams to 1.2 kilograms can be found in the human body. Can be further subdivided into metal and non-metal major minerals.MAJOR MINERALS
Required in minute amounts. Amounts ranging from 0.02 grams to 2.6 gramsTRACE MINERALS
CALCIUM, PHOSPHORUS, POTASSIUM, SULFUR, CHLORIDE, SODIUM, MAGNESIUM.MAJOR MINERALS
The most abundant metal mineral in the human body with an approximate mass of 1.2 kilograms.CALCIUM
1. Essential for muscle contraction, particularly myocardial contraction. 2. Structural function in the bones in the form of hydroxyapatite. 3. Involved in blood coagulation. 4. Functions as an electrolyte. 5. Supports the synthesis and function of blood cells.FUNCTIONS OF CALCIUM
STATE THE REGULATED SUBSTANCE OF CALCIUMcalcitonin, parathyroid hormone (PTH) and vitamin D.
increases blood Ca2+ via bone resorption.CALCITONIN
PTH and vit. Ddecreases 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 POTASSIUM1. 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 SULFUR1. 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 CHLORIDE1. 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 SODIUM1. 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 ofDNA AND RNA
STATE THE #2 FUNCTION OF MAGNESIUM2. 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 MINERALSIRON, 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 recyclingheme 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 ZINCFunctions 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 COPPER1. 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 BLOODceruloplasmin
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 MANGANESEEnzyme 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 IODINE1. Synthesis of thyroxine and triiodothyronine.
STATE THE TWO FUNCTION OF SELENIUM1. An activator of antioxidant enzymes such as glutathione peroxidases. 2. Involved in synthesis of thyroid hormones.
