Which of the following is not a property of enzymes?
|
|
Enzymes are not consumed in the reaction.
|
|
|
A small amount of enzymes is enough to catalyse a reaction.
|
|
|
Enzymes increase the activation energy of the reaction.
|
|
|
Enzymes can only work on one or a few substrates.
|
Explanation:
Detailed explanation-1: -Enzymes do not affect the free energy of reactants or products. They only reduce the amount of activation energy required for the reaction to proceed.
Detailed explanation-2: -So, the correct answer is ‘They are used up in reactions. ‘
Detailed explanation-3: -Enzymes (and other catalysts) act by reducing the activation energy, thereby increasing the rate of reaction. The increased rate is the same in both the forward and reverse directions, since both must pass through the same transition state.
