Time-dependent changes of the phosphate-metabolite concentration and the pH_i in resting (IAA, CN)-treated muscles a without and b with adrenaline applications. (Open circle, closed circle) PCr; (open triangle, closed triangle) P_i; (open inverted triangle, closed inverted triangle) G-6P; (open square, closed square) F-1,6-BP; (open diamond, closed diamond) pH_i. The open and solid symbols are the data without and with adrenaline applications, respectively, and the error bars SEM. Adrenaline was applied to muscles at the time indicated by an arrow at the top (at the start of the early phase). The concentration of F-1,6-BP is doubled for clarity. The concentration of ATP was all about 4 mM and omitted for clarity. See details in the text
