Summary The effect of a specific inhibitor of carbonic anhydrase, hydrochlorothiazide, on the content and fluxes of the principal ions in the alga Hydrodictyon reticulatum was investigated using chemical analysis and radioisotopes. Pronounced changes in the intracellular content of Na + , K + and Cl − ions after a 24-hour application of the inhibitor are correlated with the transmembrane flows of labelled ions. A diminished uptake of both protons and bicarbonate ions observed in the inhibited cells indicates changes in the intensity of photosynthesis and points to the possible role of carbonic anhydrase in the process. |
