The table below shows the blood glucose concentration of a healthy human after eating a meal containing carbohydrate.
| Time after meal (min) | Blood glucose concentration (mg/100ml) |
|---|---|
| 0 | 90 |
| 30 | 145 |
| 60 | 120 |
| 90 | 100 |
| 120 | 90 |
Using the data in the table, outline the sequence of events that occur to restore blood glucose concentration to its set point after this meal.
5 marks, so the mark scheme is looking for about 5 separate creditworthy points. Making the same point twice in different words earns it once.
Outline means: Give the main points briefly. Less detail than describe, but every key step has to be there. One short line per step, in order. The marks are for coverage, not depth.
