Question

As plasma glucose concentration rises above normal, glucose

A. Filtration increases linearly.

B. Transport maximum Tm increases linearly.

C. Clearance increases linearly.

D. Reabsorption increases and then levels ***.

E. Excretion increases and then decreases.

Answer 1

A. True Filtration rate is directly proportional to concentration.

B. False Transport maximum are constants.

C. False It *** at zero until the Tm is reached and then it rises linearly.

D. True It levels *** after Tm glucose is reached.

E. False It is initially zero and then rises linearly.
