WebI agree with all answers. EDTA is a chelator for divalent cations (Ca2+, Mg2+, Zn2+, mn2+, co2+...). It is not an inhibitor of enzyme and act mostly by decreasing the divalent … WebCompetitive inhibition. Inhibition. So the classic case of competitive inhibition: if there's some molecule that competes for the substrate at the active site, as we'll see this isn't the only form of competitive inhibition, but this is the one that you will most typically see in a textbook. So that's our enzyme again.
