<prompt> What is the net urea reabsorption rate?0 mgmin25 mgmin50 mgmin75 mgmin  <response>: 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 mLmin x 2.5 mgmL 50 mgmL x 1 mLmin 75 mgmin.
