http://chemistry.elmhurst.edu/vchembook/571lockkey.html WebThe Lock-and-key Hypothesis is a model of how Enzymes catalyse Substrate reactions. It states that the shape of the Active Sites of Enzymes are exactly Complementary to the shape of the Substrate. When a substrate molecule collides with an enzyme whose Active Site shape is complementary, the substrate will fit into the Active Site and an Enzyme ...

WebSep 16, 2024 · This model portrayed the enzyme as conformationally rigid and able to bond only to substrates that exactly fit the active site. Figure \(\PageIndex{2}\): The Lock-and-Key Model of Enzyme Action. (a) Because the substrate and the active site of the enzyme have complementary structures and bonding groups, they fit together as a key fits a lock. WebTypes of Mechanisms of Enzymes: There are two types of mechanisms involved to explain substrate-enzyme complex formation; lock and key theory (template model), and induced-fit theory. (i) Lock and Key Theory: Emil Fischer (1894) explained the specific action of an enzyme with a single substrate using a theory of Lock and Key analog (Fig. 12.11). WebThe lock and key model has many loopholes like: This experiment fails to explain the broad specificity of an enzyme. It did not explain the binding mechanism of the substrate with an enzyme. The lock and key model could not give any information about the mechanism of enzyme catalysis or product formation. Induced Fit Model how are peaches harvested commercially
