What else can I help you with?
Enzymes control this aspect of chemical reactions?
Enzymes control the rate of chemical reactions by lowering the activation energy required for the reaction to occur. This enables reactions to proceed at a faster pace and with more specificity than without enzymes. Enzymes do not change the overall equilibrium of a reaction.
Do enymes help decrease the activation energy?
Yes, enzymes decrease the activation energy required for a chemical reaction to occur. They do this by binding with the reactant molecules and stabilizing the transition state, making it easier for the reaction to proceed.
Enzymes work by lowering the what?
Also known as activation energy. threshold energy or you can also say enzymes lower the energy barrier
How does the energy of a substance change during an exothermic change?
During an exothermic change, energy is released from the substance in the form of heat to the surroundings. This results in a decrease in the internal energy of the substance, leading to a decrease in its temperature.
Do catalysts decrease or increase energy required to begin a reaction?
Catalysts decrease activation energy.
Do Enzymes increase or decrease the Activation Energy of a Chemical Reaction?
Enzymes decrease the activation energy of a chemical reaction. They do this by providing an alternative pathway with a lower activation energy that allows the reaction to proceed more rapidly.

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.
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.
What roles do enzyme play in digestion?
Enzymes are proteins that act as biological catalysts. Catalysts are substances that accelerate a chemical reaction. They decrease the activation energy of a chemical reaction.
How does the presence of enzymes affect the change in free energy during a chemical reaction?
Enzymes lower the activation energy required for a chemical reaction to occur, which in turn decreases the overall change in free energy. This allows the reaction to proceed more easily and efficiently, making it more likely to happen.
Do enymes help decrease the activation energy?
Yes, enzymes decrease the activation energy required for a chemical reaction to occur. They do this by binding with the reactant molecules and stabilizing the transition state, making it easier for the reaction to proceed.
What is activation energy and how do enzymes effect it?
There is no straight forward relation between enzyme and activation energy because although energy of reaction is fixed and is governed by laws of chemistry but for biochemical reactions concentration of enzyme and conc. of substrate affect rate of reaction and energy, but in general enzymes decrease activation energy of reaction.
How are enzymes and activation energy related?
The activation energy, once put in force, will be affected by the density, static, and kinectic energy of an object, but will still have a direct impact on the energy of reaction that is yielded from the initial force.
How do enzymes affect standard free energy?
Standard free energy doesn't change with an enzyme. Rather, the enzyme acts to redirect that reaction in a particular way, lowering the required energy for the reaction to occur but not changing the energy amount involved.
What do enzymes change about the amount of energy required to make chemical reaction occur?
Enzymes lower the activation energy required for a chemical reaction to occur. This allows the reaction to happen more quickly and efficiently by providing an alternative pathway that is energetically favorable. Enzymes do not affect the overall energy change of the reaction.
What are the effects of enzymes on activation energy?
Enzymes are believed to act by altering the pathway of the reaction so that a LOWER activation energy is present. So, it doesn't actually change the Ea of the reaction, but rather provides a "different/separate" reaction path with a lower Ea.
