A heterogeneous substance of this type has a different phase from the other molecules in the reaction.
During a portion of glycolysis, PFK acts as both a reactant and one of these substances. Within these substances, the relationship between the rate of diffusion and reaction is given by the Thiele Modulus. The effectiveness of these substances can be reduced by certain Lewis bases in a process called (*) poisoning. A heterogeneous substance of this type has a different phase from the other molecules in the reaction. In biology, these substances are called enzymes. For ten points, name this type of substance that lowers the activation energy of a reaction without participating in it.
During a portion of glycolysis, PFK acts as both a reactant and one of these substances.
