Question

Quizplus · Accepted Answer

Tubular maximum (Tm) is the maximum amount of a substance that the tubular cells can actively transport within a given time period, and it occurs when the membrane carrier becomes saturated. Therefore, both options A and C are correct. Option B is incorrect as it refers to the glomerular filtration rate (GFR), which is the amount of fluid filtered by the glomerulus per unit time.
