The phosphorylation of glucose to glucose 6-phosphate is the initial step in the catabolism of glucose. The direct phosphorylation of glucose by Pi is described by the equation 13.8 kJ/mol. The phosphorylation of glucose in the cell is coupled to the hydrolysis of ATP. Part of the energy from ATP hydrolysis is used to phosphorylated glucose. +13.8 kJ/mol -30.5 kJ/mol If the concentration of ATP is 3.38 mM and the concentration of ADP is 1.32 mM, what concentration of glucose is needed to achieve a 250 micro molar intracellular concentration of G6P?
