Classification and Functions — Predicted 2026

AI-Predicted Question Angles for UPSC 2026

Based on trend analysis, current affairs, and recurring themes in Classification and Functions.

Matching Vitamin with Coenzyme Form

high

NEET frequently tests the coenzyme roles of B-complex vitamins. A question could involve matching Vitamin B1 with TPP, B2 with FAD/FMN, B3 with NAD+/NADP+, and B6 with PLP. This tests a deeper understanding of their biochemical functions beyond just deficiency diseases. Students often memorize deficiency diseases but might overlook the specific coenzyme forms.

Symptoms of Hypervitaminosis (Fat-Soluble Vitamins)

medium

While deficiency diseases are common, questions on the toxicity of fat-soluble vitamins (hypervitaminosis) are less frequent but highly relevant. For example, asking about the effects of excessive Vitamin A (liver damage, teratogenicity) or Vitamin D (hypercalcemia, kidney stones) could be a slightly harder conceptual question to differentiate top performers. This tests the understanding of their storage properties.

Specific Dietary Sources and Unique Absorption Mechanisms

medium

Questions might focus on specific dietary sources, especially for vitamins with unique origins (e.g., B12 only in animal products) or unique absorption requirements (e.g., Vitamin B12 requiring intrinsic factor). This tests detailed knowledge beyond generic sources and emphasizes the practical aspects of nutrition. For example, a question about why vegans are prone to B12 deficiency.
