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.
After the enzyme catalyzes the reaction is it changed in any way?
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.
What end product from a metabolic pathway binds to an enzyme involved in a reaction at the beginning of the pathway. changing the shape of the active site and preventing the enzyme from?
The end product of a metabolic pathway can bind to the enzyme involved in the beginning of the pathway, acting as an inhibitor. This typically changes the shape of the enzyme's active site, preventing the enzyme from binding to its substrate and carrying out the reaction. This regulatory mechanism is known as feedback inhibition.
Compare a structure of an enzyme before and after a reation?
An enzymes structure is not affected by a reaction. The enzyme has the same structure at the end of the reaction as it did before it took place. Note: Enzyme structures may change during the reaction itself but will return to their original shape etc when the reaction is complete.
Which method of enzyme control is when the products of a reaction inhibit the working of an enzyme by binding to the enzyme?
The method of enzyme control where the products of a reaction inhibit the enzyme by binding to it is known as feedback inhibition. In this process, the end product of a metabolic pathway binds to an enzyme involved in the pathway, reducing its activity and preventing the overproduction of the product. This regulatory mechanism helps maintain homeostasis and balance within the cell.
What enzyme is person who is lactose intolerant missing?
Lactose intolerance is the inability to efficiently convert lactose into glucose and galactose, a reaction catalyzed by the enzyme lactase. (A rule of thumb for enzyme nomenclature is that many enzyme names typically take most of the name of their substrate and slap an "-ase" at the end.)
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 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.
When did Fort Nassau - South River - end?
The enzyme is unchanged by the reaction.
What is a statement that best describes an enzyme?
Enzymes are biological molecules that act as catalysts to increase the rate of chemical reactions in living organisms by lowering the activation energy needed for the reaction to occur. They are specific in their function and often end in "-ase".
After the enzyme catalyzes the reaction is it changed in any way?
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.
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.
How much catalyst remains at the end of a catalysed reaction?
At the end of a catalyzed reaction, the catalyst should remain unchanged and be present in the same amount as initially added. The catalyst works by lowering the activation energy of the reaction, facilitating the reaction without being consumed in the process.

What does the name of an enzyme tell us?
The name of an enzyme typically indicates its substrate or the type of reaction it catalyzes. Enzyme names often end in "-ase" to show that it is an enzyme. Additionally, the name may provide information about the enzyme's source or origin, such as "pepsin" from the stomach.
Is the enzyme activity same at 5 and 25 Centigrade temperature in water?
The specific activity of an enzyme at a specific temperature will be dependent on both the temperature the enzyme is operating at as well as the concentrations of the substrates (the starting materials of the reaction that the enzyme catalyzes) and products (the end materials of the reaction) present around the enzyme. However, as a general rule, the activity of an enzyme will be different at at 5 centigrade than it will be at 25 centigrade.
