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

Reaction A and B are unfavorable.

Explanation:

Gibbs free energy is an energy which that can be use to convert into useful work.

ΔG°=ΔH°-TΔS°

ΔG°= Gibbs free energy

ΔH° =  enthalpy of reaction

T = temperature of eh reaction

ΔS° = Entropy change

According to given information in the question:

Reaction A and B are non spontaneous as their Gibbs free energy value is positive.hence both are unfavorable.

a polar bond is formed when electrons are shared unevenly between atoms

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
