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.
What are the molecules that enzymes act on called?
The molecule upon which an enzyme acts is called the substrate.
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.
What can effect how the enzyme and substrate come together?
Shape of substrate, shape of the enzyme, Competitive, noncompetitive and allosteric inhibitors.
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 happens to the rate of an enzyme controlled reaction when the substrate level is high and remains high?
the enzyme will change its shape to fit the substrate correctly
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 happens to the rate of enzyme concentration when you increase substrate concentration?
The rate of enzyme reaction is increased when the substrate concentration is also increased. However, when it reaches the maximum velocity of reaction, the reaction rate remains constant.
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.
The binding together of an enzyme and a substrate forms a what?
enzyme-substrate complex
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 affect does too much substrate have on the rate of an enzyme reaction?
The enzyme becomes saturated by the substrate and enzyme activity plateaus.
The binding together of an enzyme and a substrate forms a?
The substrates are converted into products, which are released.
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 when increasing the substrate concentration when there is less substrate than enzyme?
Dunno. But this is pretty cool. But if i search the question, i obvioudly don't know it, so why would i be given an optionto answer it?
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.
