Question 3
HPerson P has Type 2 diabetes. Person Q does not have diabetes. Each person drank the same glucose solution at time 0. The concentration of glucose in their blood was then measured for 180 minutes.

a.[1]
Determine the maximum blood glucose concentration reached by person P.
b.[3]
Calculate the mean rate of decrease in the blood glucose concentration of person Q between 60 and 180 minutes. Give the unit with your answer.
c.[2]
Explain why the blood glucose concentration of person P stayed high, even though person P still produces insulin.
