Fig. 2. 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 25°C. Concentrations 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.
