What is the net urea reabsorption rate?
Correct Answer: 75 mg/min
Description: The net urea reabsorption rate is equal to the filtered load of urea (GFR x plasma urea concentration ) - urinary excretion rate of urea (urine urea concentration x urine flow rate ).
Therefore, net urea reabsorption = (50 mL/min x 2.5 mg/mL) – (50 mg/mL x 1 mL/min) = 75 mg/min.
