Question 95 from UPSC CSE 2014 - Science and Technology

Question

Consider the following pairs: Vitamin - Deficiency disease
1. Vitamin C - Scurvy
2. Vitamin D - Rickets
3. Vitamin E - Night blindness
Which of the pairs given above is/are correctly matched?

IASCODEX · Accepted Answer

Correct Option: A. 1 and 2 only

Strategy: Recall the specific disease associated with each vitamin deficiency. Vitamin C deficiency causes scurvy, and Vitamin D deficiency leads to rickets. Night blindness is caused by Vitamin A deficiency, not Vitamin E. Therefore, select the option that includes only the correct pairings for Vitamins C and D.

Key Info: - **Vitamin C (Ascorbic Acid):** Deficiency causes scurvy, characterized by bleeding gums, weakness, and impaired wound healing. It acts as an antioxidant and is essential for collagen synthesis.
- **Vitamin D:** Deficiency results in rickets in children (weak, soft, deformed bones) and osteomalacia in adults. It aids calcium absorption and bone mineralization.
- **Vitamin E:** Deficiency can cause neurological problems and hemolytic anemia. It does not cause night blindness.
- **Vitamin A:** Deficiency causes night blindness (nyctalopia) by affecting the retina's ability to process low-light images.
- **General Role of Vitamins:** Vitamins are organic micronutrients essential for metabolism. Their distinct physiological roles mean that deficiencies produce characteristic clinical syndromes, which are useful for diagnostic and preventive healthcare.
