Catalysis and Enzymatic Reactions
Catalysis is the kind of chemical reaction in which the rate (speed) of a reaction is enhanced by the catalyst which is not consumed during the process of reaction and afterward it is removed when the catalyst is not used to make up the impurity in the product. The enzymatic reaction is the reaction that is catalyzed via enzymes.
Lock And Key Model
The lock-and-key model is used to describe the catalytic enzyme activity, based on the interaction between enzyme and substrate. This model considers the lock as an enzyme and the key as a substrate to explain this model. The concept of how a unique distinct key only can have the access to open a particular lock resembles how the specific substrate can only fit into the particular active site of the enzyme. This is significant in understanding the intermolecular interaction between proteins and plays a vital role in drug interaction.

Whether equilibrium lies on the right side or left side depends upon the acidity of the reactant and product.
If reactant is more acidic than product, then equilibrium lies completely on the the right side. If product is more acidic than reactant then the equilibrium lies on left side.
The indicator for acidity is pka- value. lower the pka value , higher will be the acidity.
So, we can say if reactant has lower pka value than product, then equilibrium lies on right side.
While if product has lower pKa value than reactant, then equilibrium lies completely on the right side. If product is more acidic than reactant then equilibrium lies on left side.
