(Answer should related to The Digestive System)

Defend this statement: \"Most persons who eat a balanced diet do need to take vitamin and mineral supplements.\"

Solution

Inspite of taking balance diet we need to take extra vitamins and mineral suppliments. It is very clear that we get energy from food we take and our food is mainly constitute with carbs, protein and fat and some vitamins and minerals. But the viatmins and minerals we get from food sometimes its not sufficient for the daily need of fuctioning the vital body processes.

We need vitamiin suppliments because it is very important part of chemical reactions occuring during digestion. It acts as cofactots in the biological chemical reactions. some vitamins are water soluble (Vit B, C) and some are fat soluble(Vit A, D, E and K).

For exampe thiamine(vitamine B) serves as a coenzyme in the oxidative decarboxylation of keto acids and the formation and degradation of hydroxy ketones which is important step in fat digestion.

vitamin C (ascorbic acid) work as a cofactor in hydroxylation reaction in the formation of collagen.

FAt soluble enzymes like VIt A, D, E, K are very important as a cofactor in various processes.

Vit A (Retinol) serves as a main constituent of Ratinoic acid pathway. After its oxidation the visual pigment 11-cis-retinal is formed. Vit E is an antioxidant which prevents the oxidative damage in the cells.

Similarly minerals like Fe, Cu, Zn, Mn, Mg, Ni, Ca, K serve as cofactors and also maintain the membrane potential and muscle contration.

Fe is a cofactor in Cytochrome oxidase, Catalse, peroxidase reaction involve in the digestio.

K is a cofactor in pyruvate kinase reaction which is imporatant in carbohydrate metabolism.
