Scientists investigated the effect of a novel cinnamon bark extract, "Cinnulin-D", on blood glucose levels in diabetic volunteers.
The volunteers were divided into two groups:
- Group X: Received a placebo capsule 30 minutes before consuming a high-sucrose drink.
- Group Y: Received a Cinnulin-D capsule 30 minutes before consuming a high-sucrose drink.
At time t=0t = 0t=0 minutes, the sucrose drink was consumed. The blood glucose concentration of each group was measured over a period of 120 minutes. The results are shown in the graph below.
a.[2]
How many minutes earlier did Group Y reach its maximum blood glucose concentration compared to Group X?
b.[3]
Determine the difference between the maximum blood glucose concentration of Group X and the maximum blood glucose concentration of Group Y in mmol/dm3\text{mmol/dm}^3mmol/dm3.
