That enzymes can catalyze reactions and remain unchanged by those reactions, causing many reactions per second. Enzymes are protein machines that are reusable and rapid catalyzers.

What has no effect on the rate of an enzyme-catalyzed reaction?
When an enzyme is saturated the amount of substrate added no longer as an effect on the rate of the reaction.
What are the molecules that enzymes act on called?
The molecule upon which an enzyme acts is called the substrate.
What is the relationship between substrate concentration and enzyme activity?
At low substrate concentrations, the rate of enzyme activity is proportional to substrate concentration. The rate eventually reaches a maximum at high substrate concentrations as the active sites become saturated.
The active site of an enzyme is the location of substrate attachment?
The active site of an enzyme is a small port where substrate molecules fit. When an enzyme binds with a substrate, a chemical reaction occurs.
How is the enzyme affected during the catalyzed reaction?
The higher the substrate concentration, the higher the rate of reaction, up till the point when the limiting factor is no longer the concentration of substrate but other factors like enzyme concentration of temperature.
What has no effect on the rate of an enzyme-catalyzed reaction?
When an enzyme is saturated the amount of substrate added no longer as an effect on the rate of the reaction.
In an enzyme catalyzed reaction what is the reactant called?
Generally in an enzyme-catalyzed reaction, the reactant is called the substrate, which in association with the enzyme forms the product.
Why does it happen enzyme after it participates in a reaction?
After the enzyme has converted the substrate to the product, it is now free to accept more substrate. The enzyme does not get changed or altered in a reaction.
What is it called when and enzyme and substrate come together?
The binding of an enzyme and a substrate forms an enzyme-substrate complex. It lowers the activation energy of a chemical reaction
What affect does too much substrate have on the rate of an enzyme reaction?
The enzyme becomes saturated by the substrate and enzyme activity plateaus.
Is Vmax a threshold of substrate concentration for initiation of an enzymatic reaction?
Oddly phased question in my opinion. Vmax is only effected by the amount of enzyme present in the reaction. Substrate concentration has zero effect on Vmax. There for I believe the answer in no. {Enzyme concentration is responsible for this}
What simple experiment might you perform to test the hypothesis that an enzyme combines with its substrate when it acts?
in the absences of the enzyme the reaction is very slow,and at the end of the reaction enzyme is separated that shows substrate 1st bind to the enzyme
What happens to the enzyme after the substrate is changed?
enzyme works as a catalyst before and after the reaction it is preserved
The reactants of an enzyme-catalzyed reaction are known as what?
The substrate is the molecule affected by the enzyme.
What happens at the active site of an enzyme?
the substrate bonds to the enzyme at the active site
What is the place where the substrate attaches to the enzyme?
The active site of an enzyme is the site where substrates undergo the reaction specfic to that enzyme.
Describe the relationship between substrate concentration and the initial reaction rate of an enzyme-catalyzed reaction Is this a linear relationship What happens to the initial reaction rate as sub?
As the substrate concentration increases so does the reaction rate because there is more substrate for the enzyme react with.
