Final answer:
Carbonic anhydrase inhibitors act in the proximal tubules of the nephron.
Step-by-step explanation:
Carbonic anhydrase inhibitors act in the proximal tubules of the nephron.
The proximal tubules are located in the first part of the nephron and are responsible for the reabsorption of important substances such as glucose, sodium, and water.
By inhibiting carbonic anhydrase, these inhibitors block the conversion of carbon dioxide and water into carbonic acid, preventing the reabsorption of sodium and water in the proximal tubules.
