Why do you say that an enzyme is reusable?
Yes, an enzyme is reusable. Remember that a catalyst speeds up a reaction or lowers the activation energy without being chemically altered in the reaction. An enzyme is simply a biological catalyst so it does not change during the reaction.The only way to change an enzyme and make it unusable is if it becomes exposed to high temperatures and becomes denatured.This means the active site is damaged and the enzyme is no longer able to attach to substrates and catalyse the reaction.
How does the interaction between an enzyme and its substrate change a chemical reaction?
Enzymes speed up the chemical reactions because when it forms a complex with its substrates, it reduces the activation energy that the reaction needs to proceed. Remember that the reaction itself is not altered, only the rate of reaction, and that the enzyme is not used or altered in the reactions.
When the limiting reactant in a chemical reaction is completely used the?
reaction will stop.
Why NaOH is used as stop solution to determine specific activity of alkaline phosphatase?
This serves two functions; first, it stops the enzyme-catalyzed reaction by changing the pH to one unsuitable for the enzyme (the enzyme is denatured at high pH and so unable to function). Second, it deprotonates the p-nitrophenol to give the yellow colored p-nitrophenylate.
Can any enzyme be used in any reaction Explain?
An enzyme cannot be used in any random reaction, the active site on an enzyme can only catalyze certain substances. Think of them as keys that only work for 1 lock.
What is the function of sulphuric acid in the experiment of enzyme activity?
H2SO4 is used to denature the enzyme and stop the reaction instantly. by adding H2SO4,it will prevent further reaction of the enzyme onto the substrate and the rate of enzyme reaction can be measured in the specific time
What is the substance that identifies a substance as an enzyme?
The substance that is used to identify enzymes is hydrogen peroxide. Enzymes will catalyze the decomposition reaction of hydrogen peroxide and oxygen gas will form.
Name given to a substance used to speed up chemical reaction?
dis is the eziest question evva.....enzyme
Can enzymes be re-used?
Yes. An enzyme is a catalyst. The definition of a catalyst is "A substance that increases the rate of a chemical reaction, without being consumed or produced by the reaction." Therefore an enzyme is a catalyst and can be re-used. There are exception's in extreme tempartures of course.
What will happen to an enzyme now that is reaction completed?
The enzyme will be re-used in another reaction.
What is the difference between substrate and product?
The substrate is the substance (or substances) that attaches to the enzyme's active site before the reaction occurs.The product is the substance (or substances) that is formed after the enzyme has worked on the substrate.///
What happens or doesn't happen to an enzyme at the end of an enzymatic reaction?
The enzyme still remains and can be used again for another reaction.
What is a substance that affects the rate of a reaction without being changed or used up?
A catalyst is a substance that engages in a chemical reaction but does not remain part of the final products of the reaction. It may, however, be affected in some way as to diminish its effectiveness in further reactions.
What are the Various enzyme used in ELISA?
There is just one enzyme used in the ELISA reaction. This enzyme is linked to the secondary antibody. Commonly used ELISA enzymes are:Alkaline phosphataseHorseradish peroxidase
What is a substance that lowers the activation energy for a chemical reaction but is not changed or used up in the reaction?
This is called a catalyst. In biology, it is referred to as an enzyme (biological catalyst). Catalysts can also be used to speed up or slow down chemical reactions.
Is an enzyme a substance?
Yes, an enzyme is a substance, an organic substance, because it is a protein, and all proteins contain carbon, which is the definition of an organic substance. I had to find this out for Biology GCSE and found that not many people actually knew. Hope it helps :O)
What do you call the rate of an enzyme catalyzed reaction?
Enzymatic reaction rate, there's no term which is specifically used.
