    What was that question? I think it was something about the function and importance of glucagon was it because the insulin over shoots the set-point of 80, and some more glucose is needed for the blood?

    Sorry if I sound like an idiot, but what does it mean 'glucose over-shoots at the point of 80', we weren't taught that :/

    The experiment stated that the glucose concentration at the start was 80, whereas at the end it dropped down to 70
