Question

Which one of the following is the correct matching of the vitamin, its nature and its deficiency disease?
a. Vitamin A- Fat-soluble- Night blindness
b. Vitamin K- Fat-soluble- Beri-beri
c. Vitamin A- Fat-soluble- Beri-beri
d. Vitamin K- water-soluble- Pellagra

Answer 1

Hint: Vitamins have been divided into two categories i.e., water-soluble and fat-soluble vitamins. Vitamin B and C are water-soluble vitamins while vitamin A, D, E and K are fat-soluble vitamins.

Complete answer:
Vitamins are substances that are required by our body for its proper growth and development. Our body needs a total 13 vitamins in order to grow and develop normally. These 13 vitamins are vitamin A, B(B1, B2, B3, B5, B6, B7, B9 and B12), C, D, E and K.
Deficiency in any of the vitamins leads to certain diseases.

Each of the vitamin is discussed below:
- Vitamin A falls under the category of fat-soluble vitamins and its deficiency leads to night blindness.
- Vitamin B which comes under the category of water-soluble vitamins and its deficiency is known to cause beri-beri, pellagra,etc.
- Vitamin C falls under the category of water-soluble vitamins and its deficiency leads to scurvy.
- Vitamin D falls under the category of fat-soluble vitamins and its deficiency leads to rickets.
- Vitamin E falls under the category of fat-soluble vitamins and its deficiency leads to muscle weakness and poor transmission of nerve impulse.
- Vitamin K falls under the category of fat-soluble vitamins and its deficiency leads to bleeding disorders.

Hence, the correct answer is option (A).

Note: Vitamin A and K are fat soluble vitamins. Vitamin A is needed by the retina of the eye so the deficiency of vitamin A causes night blindness while the deficiency of vitamin K causes bleeding disorders.
