The table shows blood glucose concentrations after the same glucose drink, before and after a treatment for type 2 diabetes.
Table
| Time in minutes | Before treatment in mmol dm−3\mathrm{mmol\,dm^{-3}}mmoldm−3 | After treatment in mmol dm−3\mathrm{mmol\,dm^{-3}}mmoldm−3 |
|---|---|---|
| 0 | 6.0 | 6.0 |
| 30 | 12.0 | 10.0 |
| 60 | 11.0 | 8.0 |
| 120 | 9.0 | 6.0 |
Which conclusion is best supported?
glucose control worsened, but these results do not identify the treatment's mechanism
glucose control improved, proving that the pancreas stopped producing insulin
glucose control improved, but these results do not identify the treatment's mechanism
glucose control worsened, proving that the liver stopped producing glycogen
