Textbook Problem

To which species should an enzyme bind best: the substrate, transition state, or product of a reaction?

Interpretation Introduction


From the given species the enzyme that binds best has to be determined.

Concept introduction:

In order to establish the plausibility of a mechanism, one must compare the rate law of the rate determining step to the experimentally determined rate law.

Rate determining step: In a chemical reaction the rate determining step is the slowest step in which the rate of the reaction depends on the rate of that slowest step.

Rate law: It is generally the rate equation that consists of the reaction rate with the concentration or the pressures of the reactants and constant parameters.

Activation energy: It is defined as the minimum energy required by the reacting species in order to undergo chemical reaction.

Intermediate species: It is the species formed during the middle of the chemical reaction between the reactant and the desired product.

Enzyme: Enzymes are biological catalyst which their active site binds with the reaction in order to accomplish a reaction. The active site in enzyme is referred to the site where the takes place.


Reasons for correct option:

An enzyme is biological catalyst that is it helps the reaction to occur without involving in the reaction by reducing the activation energy of the reaction.

The enzyme generally binds with the reactants which are termed as substrate in the biological reaction. The active site binds with the substrate and results to form the products. It cannot bind with the transition state since transition state is in between state formed between the reactant and the product...
