In the first reaction of glycolysis (the pathway that begins the oxidative breakdown of sugars), the enzyme hexokinase uses atp to catalyze the phosphorylation of glucose to glucose 6-phosphate and adp. the δg° of this reaction is a favorable –4.06 kcal/mole. another sometimes active enzyme, called glucose 6-phosphatase, effectively "reverses" this reaction, hydrolyzing glucose 6-phosphate back to glucose and releasing a phosphate. the δg° of this reaction is –3.34 kcal/mole. based on these values, what is the δg° for the hydrolysis of atp: atp + h2o → adp + pi?
