Igcse Model Questions Vol1 2020 Biology Question 21
Practice objective / multiple choice question 21 from the 2020 Igcse Model Questions Vol1 Biology examination.
After a meal a student's blood glucose concentration rises to \(12\) mmol/L. For the first five minutes the pancreas secretes insulin at a constant rate of \(4\) units per minute; after five minutes insulin secretion stops. Each unit of insulin removes \(0.8\) mmol/L of glucose per minute, and cells use glucose at a basal rate of \(0.5\) mmol/L per minute regardless of insulin. Assuming no other processes, how many minutes (to one decimal place) are required for the glucose concentration to fall to the normal level of \(5\) mmol/L?
