Summary Introduction

To determine: The order of the enzymatic steps in the pathway from the given information.

Concept introduction: The reaction that has a high negative value of free energy change is the major regulatory point for metabolic pathway. The equilibrium constant represents the relation between reactants and products in a reaction at equilibrium. The concentrations of reactants and products are constant at equilibrium. The spontaneity of a reaction depends on the decrease in free energy (ΔG), that is, free energy should be negative.
