Figure 7.

Correlation between the rates of ATP and glycogen changes in presence of insulin according to the perfusate glucose concentration. The rates are expressed in nmol·min^-1·g^-1. The equation for the linear correlation is flux_glycogen = 72.543(flux_ATP) + 172.08, R² = 0.98. To obtain a positive net flux of glycogen (net synthesis), the net ATP consumption must not exceed 2.4 nmol·min^-1·g^-1.
