mechanism of enzyme by induced fit model
Answers
The enzyme ‘s active site binds to the substrate.
Increasing the temperature generally increases the rate of a reaction, but dramatic changes in temperature and pH can denature an enzyme, thereby abolishing its action as a catalyst.
The induced fit model states an substrate binds to an active site and both change shape slightly, creating an ideal fit for catalysis.
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.
In 1958,an American biologist Daniel Koshland suggested a modification to lock and key model and proposed induced fit model.According to this model,active site is not a rigid structure rather it is molded into the required shape to perform its function.Induced fit model is more acceptable than lock and key model of enzyme action.
