Question
11.18 The following plot illustrates the action of a catalyst in a chemical reaction. Original path Original activation energy New Path Reactants New activation energy Products Progress of reaction- The effect of the catalyst on the reaction is to provide a different reaction path and reduce the activation energy of the reaction. In biological systems, the most common catalysts are enzymes. Once an enzymatic reaction is completed, which of the following statements is true? ° The enzyme can be recovered once the reaction is completed because it is unchanged in the catalytic process. 0 The enzyme is consumed in the reaction. QUESTION 6 The following plot is a sketch of a reaction profile for a reaction with three steps labeled A, B, and C on the plot.Explanation / Answer
Ans 5 : The enzyme can be recovered once the reaction is completed because it is unchanged in the catalytic process.
Enzymes are called as the biological catalysts of our body. They increase the rate of reaction without themselves geeting actually consumed in the reaction, though their physical state can be altered.
They lower the activation energy barrier of the reaction , so that more number of substrate molecules can pass it and become converted into products.
