The Michaelis-Menten equation is an expression of the relationship between the initial velocity Vo of an enzymatic reaction and substrate concentration [S]. There are three conditions that are useful for simplifying the Michaelis–Menten equation to an expression from which the effect of [S] on the rate can be more readily determined. Match the condition (e.g., [S] = Km) with the statement or statements that describe it. Doubling [S] will almost double the rate. Half of the active sites are occupied by substrate. About 90% of the active sites are occupied by substrate. Doubling [S] will have little effect on the rate. Less than 10% of the active sites are occupied by substrate. This condition will result in the highest rate. Answer Bank [S] = 0.1 Km [S] = Km [S] = 10 Km

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.
