The phosphorylation of glucose to glucose 6-phosphate is the initial step in the catabolism of glucose. The direct phosphorylation of glucose by
P_(i)is described by the equation
Glucose +P_(i)longrightarrow glucose 6-phosphate +H_(2)O,\Delta G^('@)=13.8k(J)/(m)olCalculate the equilibrium constant for the phosphorylation of glucose to glucose 6-phosphate at
37.0\deg C.
K_(eq )^('),M^(-1)In the rat hepatocyte, the physiological concentrations of glucose and
P_(i)are maintained at approximately
4.8mM. What is the equilibrium concentration of glucose 6-phosphate (G6P) obtained by the direct phosphorylation of glucose by
P_(i)?
