Answer

Explanation:

Step1: Understand energy - favorability

Energetically favorable reactions have negative $\Delta G$ values (negative change in Gibbs free - energy). Larger negative $\Delta G$ values mean more favorable reactions. Endergonic reactions (unfavorable) have positive $\Delta G$ values.

Step2: Analyze each reaction

  1. Glucose to Glucose - 6 - P has $\Delta G= + 3.3$ kcal/mol, an endergonic (unfavorable) reaction.
  2. Glucose - 6 - P to Fructose - 6 - P has $\Delta G =+ 0.4$ kcal/mol, also endergonic.
  3. ATP to ADP and Pi has $\Delta G=-7.3$ kcal/mol, an exergonic (favorable) reaction.
  4. PEP to pyruvate has $\Delta G=-14.8$ kcal/mol, a highly exergonic reaction.

Answer:

  1. Glucose to Glucose - 6 - P
  2. Glucose - 6 - P to Fructose - 6 - P
  3. ATP to ADP and Pi
  4. PEP to pyruvate
