Hydrogen ions (free protons) are a constant threat to the survival of our
cells and therefore our lives. .what mechanism do the kidneys
possess that allow the quick removal of extracellular acid (via urine)?
44.
A. The filtration of protein allows free protons to be captured and removed
in the urine.
B. Reabsorption of filtered protein allows more extracellular buffers.
C. The secretion of hydrogen ions allows for the urinary removal of
extracellular acid.
D. The renal-colonic mechanism allows hydrogen ions to be removed via
the feces.
