Explain why inulin is used to measure glomerular filtration rate (GFR).

What will be an ideal response?


Answer: Inulin is a plant carbohydrate that is filtered at the glomerulus but is not reabsorbed or metabolized. Therefore, GFR = (urine concentration of inulin * volume of urine produced per unit time) / plasma concentration of inulin.
