WebThe basal reabsorption of the cryptonephric complex is blocked when treated on the lumen side with bafilomycin A(1), an inhibitor of the H(+)-ATPase, or with amiloride, an inhibitor of the H(+)/K(+) antiporter. However, the antidiuretic-factor-stimulated fluid reabsorption is not affected by either bafilomycin A(1) or amiloride.
