Worked Solution & Example Answer:People with diabetes cannot always control the concentration of glucose in their blood - Edexcel - GCSE Biology - Question 8 - 2023 - Paper 2
Step 1
Describe two differences in the concentration of glucose in the blood of the two people shown in Figure 15.
Answer
-
The blood glucose concentration for the person with diabetes is always higher compared to the person who does not have diabetes.
-
The concentration of glucose for the person with diabetes does not return to pre-meal levels within the six-hour period, unlike the person without diabetes.
Step 2
Calculate the maximum increase in the concentration of glucose in the blood of the person with diabetes.
Answer
The maximum increase in the concentration of glucose in the blood of the person with diabetes can be calculated from the graph. By identifying the peak level reached after eating the meal and subtracting the baseline level, we find the maximum increase to be approximately 10 mmol per dm³.
