Question

Renal tubular acidoses are conditions (often inherited) in which impaired renal acid excretion develops in otherwise normally functioning kidneys, leading to a metabolic acidosis.

All of the following are plausible mechanisms for renal tubular acidoses EXCEPT

Renal tubular acidoses are conditions (often inherited) in which impaired renal acid excretion develops in otherwise normally functioning kidneys, leading to a metabolic acidosis. All of the following are plausible mechanisms for renal tubular acidoses EXCEPT O a decrease in carbonic anhydrase activity (enzyme that catalyzes CO2+ H20 HCO3 O a decrease in reabsorption of metabolic acids from the tubule into the bloodstream. O a decrease in bicarbonate reabsorption from the tubule into the bloodstream H+ a decrease in acid secretion into the renal tubule.

Explanation / Answer

The probability that does not lead to metabolic acidosis is a decrease in reabsorption of metabolic acids from the tubule into the bloodstream.
