This major positive intracellularion is essential to nerve transmission, muscle contraction and plays a pivotal role in regulating fluid balance. (1/2 pt) 7. The mineral is active in many enzyme systems that plays a part in bone structure, ATP stabilization and nerve and muscle function Processed foods generally are poor sources but water from areas with hard water, may have a significant amount of this mineral. The absorption of this mineral also may be enhanced to a small extent by the presence of vitamin D. This mineral affects the metabolism of calcium, sodium and potassium. (1/2 pt) 8. The most abundant mineral in the body, found primarily in bones and teeth is A major mineral found mostly in the body's bones and teeth which is part of cell membranes, part of ATP and DNA is _-(Ipt) 9. The deficiency of the mineral can reduce the production of thyroid hormones, possibly resulting in enlargement of the thyroid gland, called a __(pt) 10. What is the dietary iron of food sources not associated with hemoglobin called? Mainly in which type of cells is this found? (pt) 11. What is the iron containing portion of hemoglobin and myoglobin molecules called? Mainly in which type of cells is this found? (1 pt) 12. A dangerous dilution of the boy's fluids, usually from excessive ingestion of plain water, is called (1/2pt)

Answer 1

6. Potassium play a major role in depolarization and resting membrane potential ( Nerve transmission) and it also help in initiation and stopping of muscle contraction. It is the most abundant positively charged (Cation) ion inside cells

Hence answer is Potassium

7. Magnesium is a cofactor, activates many enzymes and it essential for neuromuscular activity. It has major relation with calcium, potassium, and sodium metabolism.

Answer is Magnesium

8. Calcium in the form of calcium phosphate salts, provides hardness to the bones and teeth and it is most abundantly seen mineral in the body.

ATP is made of nucleic acid adenine, ribose sugar and 3 phosphate groups, The back bone structural component of DNA is sugar phosphate. Phospholipid is major component of lipid bilayer of cells membrane.

Answer is a) Calcium, b) Phosphate

9. Thyroid cells absorb iodine from the blood and synthesize thyroid hormones (T3 and T4) by iodination of tyrosine amino acid. So the deficiency of iodine leads decreased production of thyroid hormones and lead to enlargement of thyroid gland known as goiter

Answer is a) iodine b) goiter

10. Non-heme iron is not associated with hemoglobin, it is most abundantly seen in Plant based food sources

Hence and answer is Plant based food sources

11. Heme group is the iron containing portion of Hemoglobin and Myoglobin which helps them to carry oxygen to the cells. Hemoglobin is seen in red blood cells and myoglobin is seen in Muscle cells

Answer is a) Heme b) Red blood cells and Muscle cells

12. Excessive oral intake of plan water can reduce sodium level in the body fluid to a dangerous level by dilution it is known as water intoxication

Answer is water intoxication
