WebCompetitive and non-competitive inhibitors can be told apart by how they affect an enzyme's activity at different substrate concentrations. If an inhibitor is competitive, it will decrease reaction rate when there's not much substrate, but can be "out-competed" by … WebIt only binds to free enzyme. Increase substrate concentration can eliminate the effect of the competitive inhibitor. Competitive inhibitors change Km, but the Vmax remains unchanged (chemistry.elmhurst.edu). Non-competitive is a molecule that binds to a site different from the active site and prevents product formation.
