Question

Which pairing is not correct?
A. Vitamin D – Rickets
B. Vitamin K – Sterility
C. Thiamine – Beri-beri
D. Niacin- Pellagra

Answer 1

Hint: Vitamins are non energy-yielding organic compounds, essential for normal human metabolism, and must be applied in small quantities in the diet, they can be classified into two categories – fat-soluble vitamins that include Vitamin A, D, E, K, and B. water-soluble vitamins including Vitamin B complex and C, Vitamin ${B_1}$ (Water-soluble vitamin) is also known as Thiamine and Vitamin ${B_3}$ is known as Niacin which is also water-soluble.

Complete answer:
Vitamin K deficient individuals experience bleeding tendency due to lowering of levels of prothrombin and other clotting factors in the blood, Haematuria occurs first followed by the bleeding nose, gastrointestinal tract, and under the skin, so the pair of vitamin K and sterility is incorrect. Hence option B is correct.
Additional Information:
Ricket is softening and weakening the bones of children due to deficiency of Vitamin D or calcium ions or both, hence the pairing in option A is justified, and hence option A is incorrect.
The symptom of deficiency of Thiamine includes dry beriberi and wet beriberi, hence option C is justified and option C becomes incorrect.
Niacin deficiency causes pellagra which includes the cardinal manifestation of dermatitis, diarrhea, and dementia, hence option D is justified, so option D is incorrect.

Note:
Fat-soluble vitamins, Vitamin A, D, E, are stored in the body for prolonged periods and are liable for causing cumulative toxicity after regular ingestion of large amounts. Some of them interact with specific receptors analogous to hormones. Water-soluble Vitamins are meagerly stored and the excess is excreted with little chance of toxicity, they act as cofactors for specific enzymes of intermediary metabolism.
