Steps of Glycolysis — Predicted 2026
AI-Predicted Question Angles for UPSC 2026
Impact of specific enzyme deficiencies
highNEET often tests the functional understanding of pathways. Questions might describe a genetic deficiency in a specific glycolytic enzyme (e.g., Pyruvate Kinase deficiency) and ask about the resulting accumulation of intermediates, the impact on ATP production, or associated clinical symptoms (like hemolytic anemia in RBCs). This requires not just memorization but an analytical understanding of the pathway's flow and energy balance.
Allosteric regulation of key enzymes
mediumWhile basic regulation (e.g., PFK-1 inhibition by ATP) is commonly asked, NEET could delve deeper into specific allosteric activators or inhibitors for Hexokinase, PFK-1, and Pyruvate Kinase. For example, asking about the role of Fructose-2,6-bisphosphate in activating PFK-1 or the inhibition of Pyruvate Kinase by acetyl-CoA. This tests a more nuanced understanding of metabolic control.
Interconnections with other metabolic pathways
mediumGlycolysis is central to metabolism. Questions could link glycolytic intermediates to other pathways. For instance, asking which glycolytic intermediate is a precursor for glycerol synthesis (DHAP) or how the accumulation of a certain intermediate might affect the pentose phosphate pathway. This requires a broader, integrated understanding of biochemistry, moving beyond just the steps of glycolysis itself.
