A research team investigated two groups of people with diabetes. A comparison group did not have diabetes.
| Measurement | Group P | Group Q | Comparison group |
|---|---|---|---|
| mean increase in blood insulin concentration 30 minutes after a glucose drink (%) | 6 | 175 | 180 |
| mean increase in glucose uptake by isolated muscle cells when insulin was added (%) | 205 | 24 | 215 |
| members with excess body mass (%) | 14 | 68 | 27 |
| mean regular physical activity each week (hours) | 4.1 | 1.0 | 3.0 |
Compare how blood glucose regulation has failed in group P and group Q and how blood glucose concentration should be controlled in each group. Use the information in the table in your answer.
