BRAINCAKECompetitive Inhibition
Inhibitors are substances that interfere with the function of enzymes either directly or indirectly.
They may bind to the active site preventing the formation of enzyme substrate complexes or they may bind to an allosteric resulting in a change the shape of the active site so that the substrate is unable to bind.
