Glycolysis is the process by which energy is harvested from glucose by living things. several of the reactions of glycolysis are thermodynamically unfavorable (nonspontaneous), but proceed when they are coupled with other reactions. which of these reactions is(are) unfavorable? select all that apply.
(a) p1 + glucose → glucose-6-phosphate + h2o δg⁰= 3.30 kcal/mol
(b) p1 + fructose-6-phosphate → fructose-1.6-biphosphate + h2o δg⁰=3.9 kcal/mol
(c) atp + h2o → adp + p1 δg⁰=-7.30 kcal/mol
