Neco Model Questions Vol1 2025 Biology Question 50
Practice objective / multiple choice question 50 from the 2025 Neco Model Questions Vol1 Biology examination.
A person's fasting blood glucose is 5.0 mmol L\(^{-1}\). After a meal, the glucose concentration rises to 9.0 mmol L\(^{-1}\). Insulin secretion rises linearly with the amount of glucose above 5.0 mmol L\(^{-1}\) at a rate of 0.5 µU L\(^{-1}\) per mmol L\(^{-1}\) excess. Each µU L\(^{-1}\) of insulin increases glucose uptake by 0.8 mmol L\(^{-1}\) per hour. Assuming the insulin level quickly reaches the steady value corresponding to the post‑meal glucose and remains constant, estimate how many hours after the meal the glucose concentration will fall to 5.5 mmol L\(^{-1}\).
