Fig. 1. Concentration versus time plots of (A) phosphocreatine (PCr), (B)
inorganic phosphate (Pi), (C) adenosine triphosphate (ATP), (D)
phosphomonoesters (PME) and (F) lactate (La) at the experimental temperature
of 15°C. Concentration levels are expressed in µmol g-1
muscle wet mass. (E) Intracellular pH (pHi) versus time plots are
also shown. All data corresponding to the different experimental extracellular
pH (black, 7.9; white, 7.3; grey, 7.0) are shown. Time zero corresponds to the
beginning of anaerobiosis (arbitrarily set when the PCr peak started
decreasing sharply).
