How phosphocreatine buffers cyclic changes in ATP demand in working muscle
Abstract
1. Spatial buffering is hardly necessary for maintaining ATP concentration. 2. Temporal buffering may be essential to defend concentration of products of ATP hydrolysis. ADP would vary 4-fold and AMP would vary 16-fold during a single twitch without buffering. 3. The principal function of the transphosphorylating reaction may be to buffer temporally the concentrations of controlling reactants.
