WebAllosteric activators are part of regulatory processes of enzyme activity. The various terms associated with allosteric regulation and activators are: Enzymes: Protein molecules and biological catalysts that activate metabolic reactions. The term ‘ allosteric ’ refers to biochemical regulatory processes that involve a change in the ... WebWhat is the function of an allosteric activator? Allosteric activators can increase reaction rates. They bind to an allosteric site which induces a conformational change that increases the affinity of the enzyme’s active site for its substrate. This increases the reaction rate. What is an example of an activator?
