Glucose stimulates beta cells (pink) to produce insulin. Insulin stimulates muscle cells (orange) to take up glucose. In type 1 diabetes, beta cells cannot produce insulin. In type 2 diabetes, muscle cells cannot take up glucose. To learn more about diabetes, see this page from the American Diabetes Association: https://diabetes.org/diabetes
