INDEX NUMBER:
31. Diabetes leads to glucose in the urine because:
A. proximal tubule reabsorbs less glucose than normal.
B. proximal tubule secretes glucose instead of reabsorbing glucose.
C. blood glucose concentrations are elevated, and proximal tubule cannot reabsorb all
the filtered glucose.
D. blood glucose concentrations are elevated, causing damage to the glomerular
capillary membranes and leakage of glucose and extra fluid into the renal tubules.
