Effects of inhibitors of carbonic anhydrase on the GDPSP/C. A, Bath application of the impermeant carbonic anhydrase inhibitor benzolamide (BA) has no effect on the GDPSP, whereas a subsequent exposure to the more lipophilic carbonic anhydrase blocker ethoxyzolamide (EZA) abolishes the GDPSP. B, The GDPSC is inhibited by bath-applied EZA. C, Intracellular perfusion with BA at high concentrations does not block the generation of the GDPSP.
