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 p…
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 dist…
Question
Consider the following enzyme-catalyzed reaction: S - P Which of the following statements are correct: | When [S]<<Km, the reaction order is one. In the presence of the enzyme, the interconversion of S and P occurs more rapidly. When [S]>>Km, the reaction rate will be determined primarily by the enzyme concentration and not the substrate concentration. | When [S]<<Km, the reaction order is zero. The maximum reaction velocity is determined by the Michaelis constant, Km:
