Plasm a Glucose That Exceeds the Renal Threshold

Question

Plasm a glucose that exceeds the renal threshold
A) Means the Tm for glucose is decreased
B) Is a consequence of osmotic equilibration
C) Increases urine flow by osmotic diuresis
D) Is reabsorbed com pletely in the proxim al tubule
E) Is reabsorbed eventually in the distal tubule

Accepted Answer

When plasma glucose exceeds the renal threshold, it means that the transport maximum (Tm) for glucose reabsorption in the kidneys has been surpassed. As a result, glucose remains in the urine, drawing water with it through osmosis, which leads to an increase in urine flow, a process known as osmotic diuresis.
