Researchers investigate two people whose blood glucose concentrations remain high after carbohydrate is digested.
The researchers compare cells from each person with healthy control cells. A value of 100% is equal to the healthy control value.
| Measurement | Person R in % of healthy control | Person S in % of healthy control |
|---|---|---|
| Insulin released when glucose concentration is high | 6 | 92 |
| Glucose uptake by body cells exposed to the same insulin concentration | 97 | 38 |
Explain which type of diabetes is supported by the results for each person and how the results explain why their blood glucose concentrations remain high after carbohydrate is digested.
