Vocabulary
- Enzymes- long linear chains of amino acids that can fold
- Denaturization- a process where enzymes move to their second structure
Most enzymes can be denatured by heated or by certain chemicals. Some enzymes' denaturization is reversible, others is irreversible.
What else can I help you with?
Does the allosteric effect in an enzyme change the enzyme's function?
Yes, the allosteric effect can change an enzyme's function by altering its activity or affinity for its substrate. This modulation is often achieved by a molecule binding to a site on the enzyme other than the active site, causing a conformational change that affects the enzyme's catalytic activity.
How might a change of one amino acid at a site distant from the active site of an enzyme alter an enzyme's substrate specificity?
A change of one amino acid at a site distant from the active site of an enzyme can alter the enzyme's substrate specificity by affecting the overall conformation or stability of the enzyme. This alteration can influence how the enzyme binds to its substrate, either by modifying the shape of the active site or by impacting the enzyme's interactions with other molecules. Additionally, such a change might affect the dynamics of the enzyme, potentially enhancing or diminishing its ability to recognize particular substrates. Hence, even distant amino acid substitutions can have significant functional consequences on enzyme activity.
What are the names of the enzyme?
Hydrolases - Hydrolysis of a substrate - digestive enzyme isomerases - change of the molecular form of the substrate - famerase
What can change the way an enzyme acts?
Enzyme activity is affected by other molecules, temperature, chemical environment (e.g., pH), and the concentration of substrate and enzyme. Activators are molecules that encourage enzyme activity, and inhibitors are enzymes that decrease enzyme activity. Sometimes a cofactor is necessary for the enzyme to work.
Binding of a regulatory molecule changes the shape of the enzyme?
When a regulatory molecule binds to an enzyme, it can cause a conformational change in the enzyme's active site, either activating or inhibiting its function. This change in shape can affect the enzyme's ability to bind substrate molecules and catalyze reactions. Regulatory molecules can help control enzyme activity in response to cellular signals or changes in the environment.
If an enzyme is a protein how might you change the specificity of such an enzyme?
What an enzyme does is based on its shape, therefore you would have to change it on a molecular level in order to alter its job.
How does a noncompetitive enzyme inhibitor function to inhibit enzyme activity?
A noncompetitive enzyme inhibitor works by binding to the enzyme at a site other than the active site, causing a change in the enzyme's shape. This change makes it harder for the substrate to bind to the enzyme, reducing its activity.
How does an enzyme change how a reaction occurs?
An enzyme speeds up your reaction in your body.
What blocks enzyme activity by binding to allosteric site of an enzyme causing the enzyme's active site to change shape?
Allosteric inhibitors bind to a specific site on an enzyme (allosteric site) other than the active site, inducing a conformational change that decreases enzyme activity. This alteration prevents the substrate from binding to the active site, thus blocking the enzyme's ability to catalyze reactions.
Does the allosteric effect in an enzyme change the enzyme's function?
Yes, the allosteric effect can change an enzyme's function by altering its activity or affinity for its substrate. This modulation is often achieved by a molecule binding to a site on the enzyme other than the active site, causing a conformational change that affects the enzyme's catalytic activity.
Change in the pH should the enzyme?
A change in pH can affect enzyme activity by altering the enzyme's shape and thus its ability to bind with its substrate. If the pH deviates too much from the optimal range for that specific enzyme, it can denature, leading to a loss of enzyme activity. pH can also affect the ionization state of the amino acid side chains in the enzyme's active site, crucial for substrate binding and catalysis.
How might a change of one amino acid at a site distant from the active site of an enzyme alter an enzyme's substrate specificity?
A change of one amino acid at a site distant from the active site of an enzyme can alter the enzyme's substrate specificity by affecting the overall conformation or stability of the enzyme. This alteration can influence how the enzyme binds to its substrate, either by modifying the shape of the active site or by impacting the enzyme's interactions with other molecules. Additionally, such a change might affect the dynamics of the enzyme, potentially enhancing or diminishing its ability to recognize particular substrates. Hence, even distant amino acid substitutions can have significant functional consequences on enzyme activity.
What molecule does not change?
the strarch molecule binds to an enzyme
What are the names of the enzyme?

Activators are molecules that encourage enzyme activity, and inhibitors are enzymes that decrease enzyme activity. Sometimes a cofactor is necessary for the enzyme to work.
What changes the rate of a reaction?
* Presence of enzyme * Change in pH * Change in temperature * Change in salt concentration.
What is the difference between the lock and key model versus the induced fit model of the enzyme substrate complex?
The lock and key model means that the substrate must perfectly fit the enzyme, and the enzyme does not change. The induced fit model is different as when the substrate fits together with the enzyme, the enzyme itself will change to either join substrates together or break a substrate down.
