Gce Model Questions Vol1 2018 Biology Question 41
Practice objective / multiple choice question 41 from the 2018 Gce Model Questions Vol1 Biology examination.
A kidney filters plasma at a glomerular filtration rate of \(120 \text{ mL min}^{-1}\). The filtrate initially has an osmolality of \(300 \text{ mOsm kg}^{-1}\). The kidney concentrates the urine to an osmolality of \(600 \text{ mOsm kg}^{-1}\) by reabsorbing water but not solutes. Assuming the density of the filtrate is \(1 \text{ g mL}^{-1}\), calculate the volume of urine produced per minute.
