Question
Many metabolites are maintained at steady-state concentrations that are far from equilibrium. A comparison of Kéq and Q,
the mass-action ratio, can determine whether a metabolic reaction is far from equilibrium.
The equation for this equilibrium is,
fructose 6-phosphate + ATP = fructose 1,6-bisphosphate + ADP
Calculate Kg for this reaction at T = 25.0 °C.
