"WebCompetitive inhibitors are the only inhibitors that can be overcome by adding more substrate. Now this means that the competitive inhibitor and substrate are competing, they are in a RACE, for the active site, so adding more substrate just ups the chances that substrate binds to the active site rather than the inhibitor.
