So remember, in step one we take glucose, use up an ATP molecule neproduct of Hexokinase. We transform that into glucose six phosphate and this releases 33.5 kilojoules of energy. Step three, which is the committed step that's catalyzed by phosphorinase. In this step we transform fructose six phosphate into fructose 116 bisphosphate. And this is also an exergonic process that releases 22.2 kilojoules per kilojoules per mole of energy. And the final stop and the final step is also an exergonic process.
