In the first step of glycolysis, the given two reactions are coupled. reaction 1: glucose + p i ⟶ glucose - 6 - phosphate + h 2 o δ g = + 13.8 k j / mol reaction 2: atp + h 2 o ⟶ adp + p i δ g = − 30.5 k j / mol answer the four questions about the first step of glycolysis. is reaction 1 spontaneous or nonspontaneous?

non-spontaneous

Explanation:

The reaction which shows the removal of the terminal phosphate from the ATP is shown below:

The Gibbs' free energy change of this reaction,

For a reaction of be spontaneous,

The Gibbs' free energy change is positive which means that the reaction is energetically unfavorable. or non-spontaneous.
