What affect rates does a enzyme catalyzed reaction have?
Enzymes increase the rate of reaction by changing the reaction mechanism to one with a lower activation energy.
How much do enzymes increase the reaction rate by?
This question is too general.Enzymes work by lowering activation energies which, as a result, increase reaction rates.The amount of activation energy needed when a reaction is catalyzed is different for different reactions.
Do catalysts decrease or increase energy required to begin a reaction?
Catalysts decrease activation energy.
What will change when a catalyst is added to a chemical reaction?
A catalyst speeds up the rate of reaction, and lower the activation energy needed.
Describe the roles of a catalyst and substrate in a chemical reaction?
A catalyst is a substance that speeds up the rate of a chemical reaction. Catalysts work by lowering a reaction's activation energy.A substrate is a reactant of an enzyme-catalyzed reaction.
Do Enzymes increase or decrease the Activation Energy of a Chemical Reaction?
decrease

As temperature decreases the rate of an enzyme-catalyzed reaction also decreases why?
Just like many other chemical reactions, the rate of an enzyme-catalyzed reaction will decrease with temperature because of the decrease in the number of high energy collisions between particles.

How does activation energy affect chemical reactions?
The Arrhenius equation is: Ea = -RT ln(k/A) where Ea - activation energy R - universal gas constant ln - logarithm k - speed constant T - temperature in kelvins
How does catalyst affect the activation energy of chemical reaction?
The presence of a catalyst affects the activation energy of a reaction by lowering the activation energy, helping the reaction go faster and making it so the reaction does not have to use as much energy to fulfill the products.
Do enzymes increase the activation energy of biochemical reactions?
Enzymes speed up a chemical reaction by lowering the energy required for a reaction to procede, the Activation Energy (Ea). The overall change in energy of the reaction is unchanged, so the net amount of energy released in a reaction is not increased.
Why is MnO2 added to the decomposition of H2O2 reaction?
to decrease the activation energy
What effect does an enzyme have on a activation energy needed to start a reaction?
In chemistry it is called a catalyst. Enzymes decrease the activation energy needed to start a reaction.
