Background: In this module, Enzyme assays and kinetics were studied to understand the catalytic efficiency of binding of enzymes. Enzymes are biomolecules that act as catalysts in organisms to bring about specific biochemical reactions. As catalysts, enzymes do not act directly in the reaction, but perform necessary actions that bring about the reaction. This is often accomplished by causing conformational changes in biomolecules via influence on intermolecular forces (Hbonding, van der Waa...
