The enzyme does not undergo any permanent changes during the catalytic reaction; it simply facilitates the reaction by lowering the activation energy. At the end of the reaction, the enzyme is released unchanged and can participate in further reactions.

When an enzyme catalyzes a reaction does it become a product?
No, enzymes are not consumed or altered in the reaction they catalyze. They remain unchanged and can be used repeatedly.
Why is sand used in an enzyme rate of reaction lab?
Sand is used in an enzyme rate of reaction lab to provide a stable surface for the enzyme reaction to occur. It helps to maintain a consistent and controlled environment for the reaction by providing a solid base and preventing any unwanted movement or fluctuations. This ultimately allows for more accurate measurements and observations of the enzyme reaction rate.
What does the shape of an enzyme have to do with how well the enzyme works?
The shape of an enzyme is crucial for its function because it determines the enzyme's specificity and ability to interact with its substrate. The specific shape allows the enzyme to bind to its substrate, facilitating the reaction. Any changes in the enzyme's shape can affect its ability to catalyze the reaction effectively.
What chemical speeds up the chemical breakdown of food?
A substance that speeds the changing of food into a usable form* is called an enzyme. More generally, in any chemical context, a substance that speeds a reaction without itself being changed is called a catalyst._______________________________________*This changing of food into a usable form is called "digestion".
What is the difference between ATP synthesis and ATP synthase?
synthases do not use energy from NTP's, sythetases do! synthase can be used with any enzyme that catalyzes synthesis (whether or not it uses nucleoside triphosphates), whereas synthetase is to be used synonymously with 'ligase'.
What is a xylanase?
A xylanase is any enzyme which catalyzes the hydrolysis of xylan.
When an enzyme catalyzes a reaction does it become a product?
No, enzymes are not consumed or altered in the reaction they catalyze. They remain unchanged and can be used repeatedly.
What is a specific enzyme?
A specific enzyme is an enzyme that only changes the speed of ONE reaction. (It only acts on one particular substance that happens to be compatible with that enzyme) i.e. if enzyme A is specific to reaction A, it will change the speed of reaction A. However it will have no effect on any other reaction like reaction B or C.

What is an aminotransferase?
An aminotransferase is an enzyme that catalyzes the transfer of an amino group from an amino acid to a keto acid, typically involved in the synthesis and metabolism of amino acids. This enzyme is important for maintaining proper nitrogen balance in the body. Elevated levels of aminotransferases in the blood can indicate liver or muscle damage.
How many reactions can each type of enzyme catalyse?
Enzymes are specific and can catalyze one specific reaction or a group of closely related reactions. Generally, enzymes catalyze only one type of reaction due to their specificity for substrates and their active sites.
What kind of enzyme can increase the rate of a chemical reaction?
Any, that is their function.
What simple experiment might you perform to test the hypothesis that an enzyme combines with its substrate when it acts?
You could perform a simple enzyme activity assay. Mix the enzyme with its substrate and monitor the reaction rate over time using a spectrophotometer to measure any changes in absorbance or using a colorimetric assay to detect product formation. Compare the reaction kinetics with a control group lacking either the enzyme or the substrate to determine if the enzyme-substrate combination is necessary for the reaction to occur.

Can any enzyme be used in any reaction Explain?
No, enzymes are highly specific in their function and typically catalyze specific reactions. This specificity is due to the unique structure of the enzyme's active site, which is complementary to the specific substrate it acts on. Using an enzyme in a reaction for which it is not specific is unlikely to yield the desired result.
