What distinguishes a linear metabolic pathway from a cyclic metabolic pathway? Enzymes convert reactants into Intermediates before separate enzymes intermediates into products. The product inhibits an enzyme the pathway, slowing stopping the metabolic pathway. A linear pathway runs straight in one direction from reactant to product The last step of the pathway regenerates a reactant for the first step
