Neco Model Questions Vol1 2017 Biology Question 31
Practice objective / multiple choice question 31 from the 2017 Neco Model Questions Vol1 Biology examination.
After a meal the blood glucose concentration rises to \(9 \text{ mmol/L}\). The pancreas secretes insulin which increases glucose uptake by body cells at a rate of \(0.8 \times (G - 5)\) mmol\,L\(^{-1}\)\,h\(^{-1}\), where \(G\) is the current glucose concentration. At the same time glucagon secretion falls, reducing hepatic glucose production at a rate of \(0.2 \times (G - 5)\) mmol\,L\(^{-1}\)\,h\(^{-1}\). Assuming no other inputs and that glucose concentration cannot fall below the normal lower limit of \(4 \text{ mmol/L}\), what is the glucose concentration after 2 hours?
