4(c)Blood Glucose RegulationMedium3 marks

People with diabetes cannot control their blood glucose concentration. Figure 4.2 is a graph that shows the changes in blood glucose concentration after eating a meal in a person without diabetes and in a person with diabetes.

Figure 4.2, a graph of blood glucose concentration / mg per 100 cm³ of blood (0 to 250) against time after eating a meal / hours (0 to 6), with a key: the person without diabetes (solid line) rises from 90 to a peak of 140 at 1 hour, falls to 95 at 2 hours and stays at 90 from 2.5 hours; the person with diabetes (dashed line) rises from 120 to a peak of 200 at 1 hour, then falls slowly to 170 at 2 hours, 150 at 3 hours, 125 at 4.5 hours and 120 at 6 hours

Describe the differences between the blood glucose concentrations of the person without diabetes and the person with diabetes.
