Explanation
How Insulin Works
Insulin links rising blood glucose to cellular uptake and storage. This interactive model synchronizes pancreatic secretion, liver output, GLUT4 movement and blood-level traces, while allowing comparisons between normal physiology, insulin resistance and insulin deficiency.
Why it matters
Diabetes is not simply a high glucose number. The pattern reflects secretion, sensitivity, liver regulation, meal timing and—when needed—replacement insulin working together.
Key takeaway
Insulin coordinates glucose use and storage across the body; diabetes changes either the supply of that signal, the response to it, or both.
