Quizplus · Accepted Answer

Tubular maximum (Tm) refers to the maximum amount of a substance that can be actively reabsorbed from the filtrate by the tubular cells within a given time period. Option B is incorrect because Tm is not related to filtration at the glomerulus, but rather to reabsorption in the renal tubules. Option A and C correctly describe Tm.
