Scientists raised the blood glucose concentrations of two people to similar values. They then maintained the same concentration of insulin in each person's blood for 60 minutes.
Person P does not have diabetes.
| person | blood glucose concentration at the start in mmol dm−3\mathrm{mmol\,dm^{-3}}mmoldm−3 | blood glucose concentration after 60 minutes in mmol dm−3\mathrm{mmol\,dm^{-3}}mmoldm−3 | increase in glycogen stored by liver and muscle cells in % |
|---|---|---|---|
| P | 8.8 | 5.9 | 16 |
| Q | 8.7 | 8.0 | 3 |
Explain why the results for person Q are consistent with type 2 diabetes.
