Question

1) Assume that normal blood glucose is about 140 mg/dL following a meal. What would you expect the glucose concentration to be in the glomerular filtrate? What would you expect the glucose concentration to be in the urine?

Answer 1

1.glucose is reabsorbed at proximal convoluted tubule

2.amount of glucose is reabsorbed is 100%

4.it is absorbed through sodium glucose linked transport called 2⁰ active co trans port and after absorption Glut 2 facilitate diffusion in to blood .

5.maximum rate of glucose re absorbed in males 375mg /min and in females 300 mg/min

6.plasma concentration beyond 180-200 mg/dl begins to appear in urine .given 140mg/do glucose concentration in urine is not present .due to complete absorption in to the blood .
