Substrates and Enzyme Specificity - Jack Westin

Web• When an enzyme binds its substrate, it forms an enzyme-substrate complex. • Enzymes promote chemical reactions by bringing substrates together in an optimal orientation, thus creating an ideal chemical environment for the reaction to occur. • The enzyme will always return to its original state at the completion of the reaction. WebAt any given time, only the competitive inhibitor or the substrate can be bound to the enzyme (not both). That is, the inhibitor and substrate compete for the enzyme. Competitive inhibition acts by decreasing the number of enzyme molecules available to bind the …
