Gce Model Questions Vol1 2017 Biology Question 47
Practice objective / multiple choice question 47 from the 2017 Gce Model Questions Vol1 Biology examination.
In a subject the clearance of inulin (which is filtered but neither secreted nor reabsorbed) is 120 mL/min, giving the glomerular filtration rate (GFR). The plasma glucose concentration is 8 mmol/L. Normally 99 % of the filtered glucose is re‑absorbed in the proximal tubule. A drug reduces the efficiency of this re‑absorption to 85 % of the normal value. What is the rate of glucose excretion in mmol/min after the drug is given?
