WebSep 9, 2024 · Allosteric enzymes have activators that make them more active, whereas inhibitors make them less active. Effectors are what bind molecules together; they can be either inhibitors or activators. Effectors alter the conformational properties of enzymes when they bind to compounds. Since enzymes are biological catalysts, they speed up the reaction.
