Difficulty: MediumHuman Physiology, Health, and Diseases

Match the essential vitamins listed in List-I with their corresponding deficiency disorders listed in List-II, and identify the correct pairs:

  • Vitamin B1 (Thiamine)Beriberi (Peripheral nerve damage and muscle weakness)
  • Vitamin B3 (Niacin)Pellagra (Dermatitis, diarrhea, and dementia)
  • Vitamin C (Ascorbic Acid)Scurvy (Bleeding gums and impaired wound healing)
  • Vitamin D (Calciferol)Rickets (Bone softening and skeletal deformities in children)

Answer

Vitamin B1 (Thiamine) pairs with Beriberi; Vitamin B3 (Niacin) pairs with Pellagra; Vitamin C (Ascorbic Acid) pairs with Scurvy; Vitamin D (Calciferol) pairs with Rickets.
Each vitamin plays a specific biochemical role: Thiamine (B1) deficiency produces Beriberi; Niacin (B3) deficiency causes Pellagra; Ascorbic Acid (Vitamin C) deficiency causes Scurvy; and Calciferol (Vitamin D) deficiency leads to Rickets due to defective mineralization of bone matrix.

Step-by-Step Solution

1
Analyze Vitamin B1 (Thiamine) function and deficiency.
Thiamine is critical for carbohydrate metabolism and nerve function. Deficiency causes Beriberi.
Matches Vitamin B1 to Beriberi.
2
Analyze Vitamin B3 (Niacin) function and deficiency.
Niacin is required for cellular respiration. Deficiency causes Pellagra.
Matches Vitamin B3 to Pellagra.
3
Analyze Vitamin C (Ascorbic Acid) function and deficiency.
Ascorbic acid is necessary for collagen formation and tissue repair. Deficiency causes Scurvy.
Matches Vitamin C to Scurvy.
4
Analyze Vitamin D (Calciferol) function and deficiency.
Calciferol regulates intestinal calcium uptake. Deficiency leads to Rickets in growing children.
Matches Vitamin D to Rickets.
