Introduction:
Different types of ions and elemental minerals are required by the body. These minerals can function as transport ions, cofactors, catalysts, and many more. The bulk minerals are the ones that are required in large amounts and perform a large range of functions.
Answer to Problem 1TY
The correct answer is option (d) Ca2+ and PO42-
Explanation of Solution
Explanation/justification for the correct answer:
Option (d) Ca2+ and PO42-. The major components of bone are calcium and phosphate ions that provide rigidity and strength to the bones and therefore are very crucial component of the diet to maintain the bone density and structure. So, the correct answer is option (d).
Explanation for incorrect answer:
Option (a) Na+. Sodium ions are an important part of the extracellular and intracellular fluid and maintain the osmotic balance and the pH of the fluids, but it is not the component of bones. So, this is an incorrect option.
Option (b) Na+ and Ca2+. The calcium ions form the bone mineral density, but sodium ions participate in the osmotic regulation of the body and not in bone composition. So, this is an incorrect answer.
Option (c) Ca2+ and K+. Calcium ions are present in the bone and form a very crucial part of bone composition, but potassium is an intracellular ion helps in the osmotic balance and functioning of ligand-gated channels. So, this is an incorrect answer.
Option (e) PO42-and Mg2+. The magnesium ions are an important part of the chlorophyll in plants and are required in nerve and muscle function in humans but not in bone composition. So, this is an incorrect answer.
