Spletthe enzyme undergoes a conformational change upon substrate binding, resulting in a better fit between the enzyme and substrate. This conformational change may involve the enzyme rearranging its active site residues to accommodate the substrate, leading to increased specificity. Enzyme-substrate interactions: The specificity of an enzyme can … Splet14. mar. 2013 · Consequently, an enzyme reduces the activation energy of biological reaction, which it catalyzes. Two main theories are used to explain how enzyme-substrate complexes form. They are lock-and-key theory and induced-fit theory. Lock-and-Key Model. Enzymes have very precise shape, which includes a cleft or pocket called active sites.
