Imagine that you are setting up an experiment to measure the kinetics of an enzyme. What are TWO reasons that it is important to measure the enzyme's velocity very quickly after starting the reaction?
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.

enzyme's velocity very quickly after starting the reaction?
To capture the velocity of the reaction in the microseconds before the enzyme-substrate concentration [ES] has reached steady-state
To measure the forward velocity of the reaction with a negligible contribution from the reverse reaction
To isolate the effect of the enzyme from the uncatalyzed reaction
To measure the velocity of the reaction with a known enzyme concentration, because enzyme is irreversibly destroyed during catalysis
