by reducing the activation energy required to initiate the reaction
What else can I help you with?
Each enzyme produced by the body is?
specific to a particular substrate, meaning it catalyzes a specific chemical reaction. Enzymes are proteins that speed up biochemical reactions without being consumed themselves. Each enzyme has a specific shape that allows it to interact with a specific substrate.
What is the function of enymes?
Enzymes are biological catalysts. They speed up biochemical reaction. During the course of a reaction, the enzyme molecules do not get consumed. At the end of a reaction, the enzyme molecules are ready for another reaction. Enzymes are able to catalyze reactions by decreasing the free energy change (delta G) associated with a biochemical reaction. When the reactants have to go through a smaller free energy change, the products are formed faster.
What happens to an enzyme after it catalyzes a chemical reaction?
Enzymes are not used up in a chemical reaction. Usually, the enzyme will "reset" and be ready to use in another reaction. This is due to the fact that enzymes are proteins, and their shape is what they use in a chemical reaction. Initially, the enzyme has a particular shape. Something happens to the enzyme (usually a shape change, called a conformation change, brought on by the presence of two or more chemical reactants), and the enzyme catalyzes the reaction. After the reaction is catalyzed, the product is released, and the enzyme can "relax." This means it goes back to its normal shape, ready to do it all over again.
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.
What is the name of the Place on an enzyme where reaction occurs?
"Inside your mouth. It's like the saliva that you won't be able to taste food without."Err... lol.A enzyme reacts with a substrate at the enzyme's active site.
What is the definition of enzyme?
Enzymes are proteins that are able to catalyze (i.e accelerate) biochemical reactions. During the course of a reaction, the enzyme is able to convert a substrate to a product but the enzyme does not get consumed in the reaction.
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.
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 enzyme is produced in the stomach?
specific-meaning it is only able to catalyze a reaction with a certain molecule.
Are enzymes changed in a reaction?
No, enzymes are not changed in a chemical reaction. They remain unchanged and are able to participate in multiple reaction cycles. Enzymes act as catalysts to speed up reactions without being consumed or altered in the process.
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 kinds of chemicals can you add to speed up the action of an enzyme?
The kinds of chemicals that you can add to speed up the action of an enzyme are known as catalysts. Such catalysts, will be able to interact chemically with the enzymes in the reactions.
