← Human Body & HealthIf a patient exhibits elevated blood glucose despite consistently high insulin levels, which consequence affecting the cellular insulin receptors is most likely?
A)Receptor upregulation increases sensitivity
B)Increased GLUT4 translocation to membrane
C)Receptor desensitization reduces glucose uptake✓
D)Enhanced insulin binding affinity occurs
💡 Explanation
Receptor desensitization leads to reduced glucose uptake because the prolonged exposure to high insulin concentrations causes a decrease in receptor sensitivity, therefore cellular glucose uptake diminishes despite the presence of insulin, rather than increased sensitivity or enhanced binding affinity.
