What else can I help you with?
What does a enzyme do A Adds heat to a reaction speeding it up B Lowers the activation energy of a reaction C Cools a reaction slowing it down D Raises the activation energy of reaction?
B. Lowers the activation energy of a reaction. Enzymes facilitate chemical reactions by decreasing the energy needed to start the reaction, thus speeding up the overall process.
Can enzymes increase the rate of chemical reaction by lowering activation energy barriers?
Yes, enzymes can increase the rate of a chemical reaction by lowering the activation energy required for the reaction to occur. This allows the reaction to proceed more quickly and efficiently than without the enzyme.
Describe the effect of an enzyme on the activation energy in a chemical reaction?
Enzymes lower the activation energy required for a chemical reaction to occur by stabilizing the transition state, making it easier for the reaction to proceed. This acceleration allows reactions to occur at a faster rate and under milder conditions than without the enzyme present.
How do enzymes speed up chemical reactions?
Enzymes lower the activation energy of a chemical reaction.
What cause the activaton energy required for a chemical reaction to place is lowered in a enzyme?
If your question is ''What causes the activation energy required in a chemical reaction to lower down?'' Then my answer to your question would be that the temperature factor is either more than to what the enzymes needed or less than what is needed by the enzymes to function. However the optimum temperature mostly for an enzyme to be active at the fullest can be till 40 degrees Celsius.
Function of a enzyme?
An enzyme speeds up a chemical reaction by lowering the activation energy.
How does a enzyme increase the speed of a reaction?
The enzyme reduces the activation energy of the reaction, therefore chemical reaction speeds are increased.
What effect do enzyme have on the activation energy of a chemical reaction?
why i get to thes bage
How does an enzyme help in a chemical reaction?
It speeds up the reaction by lowering activation energy.
How an enzyme helps to speed up chemical reaction?
by lowering the activation energy
What happens when activation energy is in presence of an enzyme?
When activation energy is in the presence of an enzyme, the enzyme can lower the activation energy barrier required for a chemical reaction to occur. This allows the reaction to proceed at a faster rate and with lower energy input. The enzyme does this by stabilizing the transition state of the reaction, making it easier for the substrate molecules to react.
How does an enzyme catalyze a chemical reaction in regards to activation energy?
Any catalyst will make a chemical reaction easier or quicker to happen by lowering the activation energy. On a energy diagram, you will see a lower "hill" for activation energy, which corresponds to less energy required to begin the reaction.
What is the protein that speeds up chemical reactions by lowering the activation energy in the reaction?
Enzyme's
Why do you need a catalyst during a enzyme reaction?
A catalyst speeds up the rate of a chemical reaction by lowering the activation energy needed for the reaction to occur. In the case of an enzyme-catalyzed reaction, the enzyme serves as a biological catalyst, allowing the reaction to occur more efficiently and at lower energy levels than it would without the enzyme.
What does an enzyme do to activation energy?
Enzymes reduce the activation energy required for a chemical reaction to occur by stabilizing the transition state of the reaction. This allows the reaction to proceed more rapidly than if it were to occur without the enzyme present.
Is more energy required for a chemical reaction in the absence of an enzyme?
Without an enzyme, the activation energy needed to start a reaction is much greater. An enzyme is a catalyst, which decreases the amount of activation energy needed to start a reaction. By doing so, it decreases the amount of time the chemical reaction takes place.
What will most likely happened if an appropriate enzyme is added to a chemical reaction?
The enzyme will act as a catalyst, a compound that lowers that activation energy of the reaction, and therefore, increase the rate of the reaction.
