The initial step in the metabolic breakdown of glucose is a phosphorylation reaction. glucose + hpo42- + h+ ⟶ [glucose phosphate]- + h2o δgo = +3.3 kcal/mol but this is not spontaneous, so it is coupled with a reaction that is spontaneous. all organisms use the hydrolysis of atp to adp to drive this process. atp4- + h2o ⟶ adp3- + hpo42- + h+ δgo = -7.3 kcal/mol therefore, what is the δgo for the following overall reaction? glucose + atp4- ⟶ [glucose phosphate]- + adp3- δgo = ? a. -5.3 kcal/mol b. -10.6 kcal/mol c. -4.0 kcal/mol d. -8.0 kcal/mo
