Gce Model Questions Vol1 2019 Biology Question 45
Practice objective / multiple choice question 45 from the 2019 Gce Model Questions Vol1 Biology examination.
In the renal glomerulus the following pressures are measured: glomerular capillary hydrostatic pressure \(P_{gc}=55\) mmHg, Bowman's capsule hydrostatic pressure \(P_{bc}=15\) mmHg, and plasma oncotic pressure \(\pi_{gc}=30\) mmHg. The filtration coefficient \(K_f\) is \(12.5\) mL min\(^{-1}\) mmHg\(^{-1}\).\n(a) Calculate the glomerular filtration rate (GFR) under these conditions.\n(b) A drug reduces \(K_f\) by 20 % and raises plasma oncotic pressure by 5 mmHg. What is the new GFR? Give your answers in mL min\(^{-1}\).
