Quodase is an enzyme that is used as a catalyst in a reaction involving quoddic acid. Aliumic acid has an almost identical shape to quoddic acid and can bind to the active site of the quodase. keeping quoddic acid from binding in this example aliumic acid is- (A) the substrate
This is an example of enzyme catalysis reaction. catalysts are found in the form of enzymes. enzymes are proteins that are able to lower the activation energy for various biochemical reactions. they do this by binding the reactant(s), known as the substrate(s). to an active site with the enzyme. here, aliumic acid can bind to the active site of quodase so this is a straight example of the substrate. At the active site, the substrate can form an activated complex at lower energy. further the enzymes are free to catalyze more reaction when it once complete the reaction then the product leaves the active site.

Question 1 2 pts How does a noncompetitive inhibitor decrease the rate of an enzyme-catalyzed reaction? by decreasing the free-energy change of the reaction catalyzed by the enzyme by binding to an allosteric site, thus changing the shape of the active site of the enzyme by binding to the active site of the enzyme, thus preventing binding of the normal substrate by binding to the substrate, thus changing its shape so that it no longer binds to the active site...
