## Question 3.3.4 (3 marks)

Normal blood glucose: 3,9 to 5,6 mmol/ℓ.
Normal insulin 60 minutes after glucose: 18 to 276 mU/ℓ.

Time after drinking glucose (minutes): 0 | 60 | 120
Group P, average glucose (mmol/ℓ): 4,6 | 6,4 | 4,7
Group P, average insulin (mU/ℓ): 9 | 150 | 105
Group Q, average glucose (mmol/ℓ): 7,0 | 9,1 | 8,9
Group Q, average insulin (mU/ℓ): 4 | 3 | 3

A study looked at how insulin affects blood glucose. Two groups of eight adults each drank 75 g of glucose. Group P was healthy. Group Q had diabetes. Blood was sampled before the drink and again 60 and 120 minutes later. Using data from the table, explain why Group Q is the group with diabetes.
