We used 31P NMR to investigate the temperature-dependence of intracellular pH (pH i ) in isolated frog skeletal muscles. We found that ln[H+ i ] is a linear function of 1/T abs paralleling those of neutral water (i.e., H+= OH−) and of a solution containing the fixed pH buffers of frog muscle cytosol. This classical van't Hoff relationship was unaffected by inhibition of glycolysis and was not dependent upon the pH or [Na+] in the bathing solution. Insulin stimulation of Na+-H+ exchange shifted the intercept in the alkaline direction but had no effect on the slope. Acid loading followed by washout resulted in an amiloride-sensitive return to the (temperature dependent) basal pH i .
