Enzymes are highly efficient catalysts, and only small quantities are needed to catalyze the reaction of relatively large amounts of materials.
What else can I help you with?
Is it true that after the product of an enzyme-catalyzed reaction leavesthe active site the enzyme can no longer react with more substrate?
No, after the product of an enzyme-catalyzed reaction leaves the active site, the enzyme can still react with more substrate to continue catalyzing the reaction. The enzyme is not altered or used up in the reaction, so it can continue to bind to and catalyze additional substrate molecules.
An enzyme speeds up a chemical reaction in the cell but can only be used one?
Actually, enzymes are not used up in chemical reactions; instead, they can catalyze multiple reactions over time. They lower the activation energy required for reactions, allowing them to proceed more quickly. After facilitating a reaction, the enzyme is released unchanged and can be reused to catalyze additional reactions. This efficiency is a key reason why enzymes are essential for biological processes.
What is the reactants of an enzyme-catalyzed reaction known as?
Reactants. "Substrate" is another possibility.
When an enzyme catalyzes a reaction does it become a product?
biological catalysts known as enzymes are molecules that lower the amount of energy required to kick start a reaction and are NOT used up or changed in the reaction.
Why only a small amount of enzyme is needed to catalyse a reaction involving many molecoles?
The principle reason a little bit of enzyme can catalyze a reaction involving many molecules is that enzymes are not consumed by the reactions they catalyze. Enzymes are typically multi-use entities and will continue acting until all substrates are reacted.

No, after the product of an enzyme-catalyzed reaction leaves the active site, the enzyme can still react with more substrate to continue catalyzing the reaction. The enzyme is not altered or used up in the reaction, so it can continue to bind to and catalyze additional substrate molecules.
Do enzymes get used up in a reaction, or do they remain unchanged and available to catalyze multiple reactions?
Enzymes remain unchanged and available to catalyze multiple reactions. They are not used up in a reaction.
The ability of an enzyme to catalyze a reaction is not affected by?
The ability of an enzyme to catalyze a reaction is not affected by changes in temperature or pH within a certain range known as the enzyme's optimal conditions. However, extreme changes in temperature, pH, or enzyme concentration can denature the enzyme and affect its activity. Additionally, the substrate concentration can affect the rate of reaction up to a point of saturation, where all enzyme active sites are occupied.
Which is not true of enzyme behavior?
Each enzyme can catalyze a wide variety of different reactions.
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.
What is the reactants of an enzyme-catalyzed reaction known as?
Reactants. "Substrate" is another possibility.
What is part of an enzymes name usually derive from?
Enzymes speed up chemical reactions that take place in cells. They are usually named from the reaction that they catalyze.
When an enzyme catalyzes a reaction does it become a product?
biological catalysts known as enzymes are molecules that lower the amount of energy required to kick start a reaction and are NOT used up or changed in the reaction.
Which is accurately describes an enzyme?
An enzyme is a biological catalyst that speeds up chemical reactions in living organisms by lowering the activation energy required for the reaction to occur. Enzymes are highly specific, meaning they only catalyze one particular reaction or a group of closely related reactions. They are not consumed in the reaction and can be used repeatedly.
Why only a small amount of enzyme is needed to catalyse a reaction involving many molecoles?
The principle reason a little bit of enzyme can catalyze a reaction involving many molecules is that enzymes are not consumed by the reactions they catalyze. Enzymes are typically multi-use entities and will continue acting until all substrates are reacted.
What simple experiment can you perform to test the hypothesis that an enzyme is not used up during the reaction?
To test the hypothesis that an enzyme is not used up during a reaction, you can perform a simple experiment where you measure the enzyme activity before and after the reaction. If the enzyme activity remains the same before and after the reaction, it indicates that the enzyme is not used up. This can be done by measuring the substrate conversion rate or product formation rate.
How did the use of a lower enzyme concentration affect your experiment If your experiment did not work as expected what should have happened?
Using a lower enzyme concentration would result in a slower rate of reaction because there are fewer enzymes available to catalyze the reaction. If the experiment did not work as expected, increasing the enzyme concentration could have potentially sped up the reaction and led to the expected results.
