Between the renal threshold and T-Max the amount of glucose filtered and the amount of glucose in the urine is not linearly related. This is becuase some nephrons have a greater capacity for reabsorbtion than others and are not overcome as easily.</FONT></TD>

Is the point at which every nephron is running at full capacity of reabsorping glucose. After this point the glucose cocentration filtered and excreted increase linearly.</FONT></TD>
