Waec Model Questions Vol1 2017 Biology Question 19
Practice objective / multiple choice question 19 from the 2017 Waec Model Questions Vol1 Biology examination.
After a meal a student's blood glucose concentration rises to 180 mg dL⁻¹. Insulin secretion causes glucose uptake by cells at a rate proportional to the excess glucose above the normal fasting level of 100 mg dL⁻¹, with a proportionality constant of 0.5 min⁻¹. Glucagon secretion is suppressed, so endogenous glucose production is negligible. Assuming the rate of decrease of glucose concentration follows the differential equation dG/dt = -0.5 (G - 100), how many minutes will it take for the glucose concentration to fall to 110 mg dL⁻¹?
