The standard free energy change of the glycolytic pathway to pyruvate is -79.9 kj/mol, while the standard free energy change associated with gluconeogenesis from pyruvate is -42.7 kj/mol. what would the standard free energy change be for a direct reversal of the glycolytic pathway?

122.7 kj/mol

Explanation:

This is purely theorical because it is not possible to accomplish the reversed pathway of the gycolytic pathway, but you would only need the same amount of energy but in reverse, this is in theory, in order to reverse the pathway. Standard free enegy is the amount of energy needed to create one mole of a given substance in its most stable form.
