thus , although the phosphorylation state of the adenine nucleotide pool remained only moderately perturbed , if at all , there were decreases in tissue concentrations of phosphocreatine and glycogen , and increases in those of cyclic amp , lactate , and pyruvate , with a calculated fall in intracellular ph of about 0.15 units and a rise in the cytoplasmic nadh/nad+ ratio .
