1. The properties of the systems that regulate intracellular pH (pHi) in frog muscle (Rana pipiens) were studied in semitendinosus fibres using pH-sensitive micro-electrodes. All experiments were done at 22 degrees C and at external pH (pHo) 7.35. 2. Normally polarized fibres acidified to pHi approximately 6.8 by an NH4Cl pre-pulse (nominal absence of CO2) recovered at a rate of 0.26 +/- 0.04 delta pHi h-1 (n = 10). This corresponds to a net equivalent H ion efflux, JH, of 5.0 pmol cm-2 s-1… CONTINUE READING
