Gce Model Questions Vol1 2024 Biology Question 36
Practice objective / multiple choice question 36 from the 2024 Gce Model Questions Vol1 Biology examination.
An adult fasting has a blood glucose concentration of \(5\ \text{mmol L}^{-1}\). After eating a meal containing \(60\ \text{g}\) of carbohydrate, only \(80\%\) of the carbohydrate is absorbed. Each gram of absorbed carbohydrate raises blood glucose by \(0.1\ \text{mmol L}^{-1}\). Insulin secretion rises linearly with the increase in glucose above \(5\ \text{mmol L}^{-1}\) at a rate of \(0.5\ \mu\text{U mL}^{-1}\) for every \(0.5\ \text{mmol L}^{-1}\) rise. Each \(\mu\text{U mL}^{-1}\) of insulin lowers glucose by \(0.2\ \text{mmol L}^{-1}\) per hour, and insulin clearance is negligible during the first hour. What is the expected blood glucose concentration after one hour (to two decimal places)?
