Serosal Na/Ca exchange and H super(+) and Na super(+) transport by the turtle and toad bladders

A Na/Ca exchange system has been described in the plasma membrane of several tissues and seems to regulate the concentration of calcium in cytosol. The results of the present studies strongly suggest that an increase in cytosolic calcium through the serosal Na/Ca exchange system inhibits H super(+)...

Description
Summary:A Na/Ca exchange system has been described in the plasma membrane of several tissues and seems to regulate the concentration of calcium in cytosol. The results of the present studies strongly suggest that an increase in cytosolic calcium through the serosal Na/Ca exchange system inhibits H super(+) and Na transport in the turtle and toad bladder probably by increasing the resistance of the luminal membrane.
