Which statement correctly describes tubular maximum (T_m)? A)It is the rate of glomerular filtration. B)It is the rate at which a substance can be reabsorbed because of saturation of the carrier molecule. C) It is the rate at which a substance can be cleared from the blood. D) It is the percentage of renal blood flow that can be converted to filtrate.

Question

Quizplus · Accepted Answer

Tubular maximum refers to the maximum rate at which a substance can be reabsorbed by the renal tubules. This occurs because the carrier molecules in the tubules become saturated with the substance, and any excess is excreted in the urine. Therefore, option B is correct as it describes the concept of tubular maximum accurately. The other options are incorrect as they refer to different concepts, such as glomerular filtration rate (option A), clearance rate (option C), and renal blood flow (option D).
