Enzymes alter ∆G for a … WebAway from the active site, enzymes can be either activated or inhibited when substances different than the substrate (heterotropic effectors) bind and induce different physical states (shapes, as it were) in an enzyme. These shifts alter the ability of the binding site to collect and hold substrate.
