Enzymes — Predicted 2026

AI-Predicted Question Angles for UPSC 2026

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

Graphical interpretation of enzyme kinetics with inhibitors

high

NEET frequently uses graphs to test understanding of enzyme activity. A common advanced question type involves presenting Lineweaver-Burk plots or Michaelis-Menten curves and asking students to identify the type of inhibition (competitive, non-competitive) based on how $V_{max}$ and $K_m$ are affected. This requires not just memorization of effects but also the ability to interpret graphical data accurately. Questions might also involve comparing two enzymes under different conditions on a single graph.

Role of specific cofactors/coenzymes in metabolic pathways

medium

While general questions on cofactors are common, NEET could delve deeper by linking specific coenzymes (e.g., NAD$^+$, FAD, Coenzyme A) to their roles in particular metabolic pathways (e.g., glycolysis, Krebs cycle, fatty acid synthesis). This would test integrated knowledge of enzymes with other chapters like 'Respiration in Plants' or 'Human Physiology (Digestion and Metabolism)'. Students might be asked to identify which coenzyme is involved in a specific step or reaction type.

Allosteric regulation and feedback inhibition in metabolic control

medium

Allosteric regulation and feedback inhibition are crucial mechanisms for controlling metabolic pathways, ensuring efficiency and preventing wasteful overproduction. While often covered conceptually, NEET could present a simplified metabolic pathway and ask how the end-product regulates an initial enzyme via allosteric feedback inhibition. This tests the understanding of enzyme regulation beyond just simple competitive/non-competitive inhibition, emphasizing the dynamic control of cellular processes.

Enzyme classification and specific examples from human body

high

Questions linking enzyme classes to specific examples from human physiology (e.g., digestive enzymes, enzymes in blood clotting, or metabolic enzymes) are always relevant. For instance, identifying a hydrolase involved in protein digestion or a ligase involved in DNA repair. This tests both classification knowledge and application to biological systems, which is a core NEET focus.
