What simple experiment can you perform to test the hypothesis that an enzyme is not used up during the reaction?
Add more of the reactants under appropriate reaction conditions. If more product is made, this shows that the reactants are the limiting component and not the enzyme.
Are the enzymes used up by the reaction?
an enzyme does not get used up in a reaction. it is essentially a catalyst. although an enzyme speeds up the rate of chemical reactions by decreasing the amount of activation energy required, it does not in itself change during the reaction.***Note:: Enzymes cease to function when they denature. This usually occurs by pH level changes, or increased temperatures. This occurs because it causes the bond of the molecule to break and essentially changes the shape of the enzyme. Because an enzyme is a lock and key model, when the shape changes it becomes uselesssources: my brain
How many times can one enzyme be used?
Each enzyme molecule is used over and over again. One of the fastest enzymes is catalase, which is found in liver and elsewhere. It catalyzes the breakdown of hydrogen peroxide into water and oxygen: 2H2O2 forms 2H2O + O2 Each molecule of catalase catalyzes the breakdown of some 40 million substrate molecules in a second.
A biological catalyst capable of speeding up a chemical reaction is known as what?
A lot of homework questions, today. I wouldn't answer but the questions are always written poorly due to teachers not understanding their subject matter. Your teacher probably wants you to say "An enzyme." http://en.wikipedia.org/wiki/Enzyme
What specific proteins are responsible for speeding up the rate of chemical reactions?
"Catalysts", in general chemical terms, but in living organisms they are usually called "enzymes".
How does pH affect enzyme functions?
Enzymes lower the amount of Activation Energy needed for a chemical reaction, therefore speeding up the chemical reaction. For an enzyme to do this it needs to be at the correct pH, salinity, and temperature otherwise the enzyme will not be able to work. When an enzyme is in a pH that is not suitable, the enzyme's shape and structure alter and make it unable to speed up a reaction.
Can enzymes be used once?
Enzymes are biological catalysts, and like all catalysts they have the property of affecting some chemical reaction (normally, either speeding it up or slowing it down) without being used up or altered in the process. They can be re-used. Indeed, it is often necessary to use some antagonistic enzyme to halt the action of a given enzyme when it has done enough of what it is supposed to do.
What makes enzymes speed up the chemical rate?
The ability to attract similar molecules that bond, whereas without the enzyme, the molecules would have to hit in a same position at the exact molecule needed for bonding. An enzyme is able to do this many times in a second, thus speeding up the reaction.
What simple experiment can you perform to test the hypothesis that an enzyme is not used up during the reaction?
Add more of the reactants under appropriate reaction conditions. If more product is made, this shows that the reactants are the limiting component and not the enzyme.
Is it true that Enzymes are not consumed during a chemical reaction?
Correct. Enzymes help to speed up chemical reactions. They may speed them up, costing them some energy, but they are never used up.
How are catalysts used in technology?
by speeding up the experiments having to do with chemical reactions
What is a coproccessor driver used for?
A co-processor driver is used for controlling the co-processor which aids your CPU in carrying out some functions such as speeding up media such as graphics and speeding up the number of calculations your CPU can handle.
How do you prove that carbon dioxide is produced during fermentation?
Do it a lot and check if global warming is speeding up.

What is the fucntion for a enzyme?
Enzymes are used to speed up chemical reactions. One example of an enzyme is lactase which speeds the the digestion of lactose.
What is a catalase?
Hello there! Catalase is a common enzyme found in organisms exposed to oxygen. It plays an important role in speeding up or catalysing, decomposition of hydrogen peroxide into oxygen and hydrogen. In this way, the enzyme protects you from the damage of free radicals like hydrogen peroxide. Hopefully, this helped you! 😊👍
What is another name for a protein catalysts that speeds up chemical reactions during cellular respiration?
An enzyme
