WebNov 3, 2016 · Enzymes: Basic terminology and concepts. A catalyst is a substance that speeds up the rate of a chemical reaction without itself being consumed or generated by the reaction. An enzyme is a protein that acts as a catalyst. The term substrate refers in enzymology to a reactant in an enzyme-catalyzed reaction. WebThe competitive inhibitor binds to the active site and prevents the substrate from binding there. The noncompetitive inhibitor binds to a different site on the enzyme; it doesn't block substrate binding, but it causes other changes in the enzyme so that it can no longer catalyze the reaction efficiently. joanne feldman wikipediaWeb20 hours ago · The larger binding pocket may promote the conformational sampling of the substrate and increase the frequency of productive binding modes 33, thereby … in-stream ads eligible country
