Answer 1

1). Vision; maintenance of cornea, epithelial cells, skin – Vitamin A

Explanation: Vitamin A is essential for the maintenance of cell function, normal vision, for growth, erythrocyte production, epithelial integrity, reproduction, and functioning of the immune system.

2). Growth; regulation of gene expression; reproduction – Vitamin E

Explanation: dietary vitamin E could improve the concentration of reproductive hormones in serum and the expression of reproductive hormone receptor genes in the ovary.

3). Mineralization of bones and teeth – vitamin D

Explanation: vitamin D is essential for the absorption of calcium.

4). Antioxidant – Vitamin C and E.

Explanation: vitamin C or E that removes potentially damaging oxidizing agents in a living organism.

5). Synthesis of blood clotting proteins and bone proteins – vitamin K

Explanation: The body needs vitamin K for the synthesis of certain proteins that are required for the process of blood coagulation.

6). Collagen synthesis – vitamin C

Explanation: The antioxidant properties of vitamin C (ascorbic acid) and its function in collagen production make vitamin C an essential molecule for skin health.

7). Restores Vitamin E to active form – vitamin C

Explanation: Vitamin C recycles and thus preserves vitamin E or alpha-tocopherol in cell membranes.

8). Coenzyme in energy metabolism - Thiamin, riboflavin, niacin, Vit B12, B6

Explanation: The B complex of vitamins consist of thiamin (vitamin Bl), niacin, riboflavin, vitamin B6, folate, vitamin B12, biotin, and pantothenic acid.

9). Part of a coenzyme for new cell synthesis – Vit B12, Vit B13, riboflavin, Vit C

Explanation: Vitamins B-12, B-13, and C are all precursors of electron-carrying coenzymes.

10). to maintain nerve cells – Vit B12

Explanation: Vitamin B12 is essential for the strong protection of the nerves.
