Insulin and Glucagon — Predicted 2026
AI-Predicted Question Angles for UPSC 2026
Detailed mechanism of GLUT4 translocation and its clinical relevance.
highNEET is increasingly focusing on cellular and molecular mechanisms. Understanding how insulin facilitates glucose uptake via GLUT4 in muscle and adipose tissue is a key mechanism. Questions could explore the signaling pathway, the tissues involved, or the implications in insulin resistance (Type 2 Diabetes), making it a high-yield conceptual area.
Role of C-peptide in differentiating Type 1 vs. Type 2 Diabetes.
mediumWhile the basic distinction between T1DM and T2DM is often tested, the diagnostic utility of C-peptide levels is a slightly more advanced application. Questions could present a clinical scenario and ask how C-peptide measurement aids in diagnosis, requiring a deeper understanding of insulin synthesis and secretion.
Interplay with other hormones regulating glucose, such as amylin or incretins (GLP-1, GIP).
mediumBeyond insulin and glucagon, other hormones like amylin (co-secreted with insulin) and incretins (gut hormones that enhance insulin secretion) play roles in glucose homeostasis. NEET might introduce questions that integrate these lesser-known but relevant hormones to test a broader understanding of glucose regulation, especially given the increasing focus on GLP-1 agonists in diabetes treatment.
Specific enzyme regulation by insulin and glucagon (e.g., glycogen synthase, glycogen phosphorylase, PFK-1, FBPase-1).
lowWhile the general pathways (glycogenesis, gluconeogenesis) are high yield, questions delving into the specific enzymes regulated by insulin and glucagon (e.g., through phosphorylation/dephosphorylation cascades) are more typical of advanced biochemistry. However, a basic understanding of key regulatory enzymes like glycogen synthase (activated by insulin) and glycogen phosphorylase (activated by glucagon) could be tested in a conceptual manner.
