What is the difference between an allosteric inhibitor and a competitive inhibitor in terms of their mechanisms of action on enzyme activity?
An allosteric inhibitor binds to a site on the enzyme that is separate from the active site, causing a change in the enzyme's shape and reducing its activity. A competitive inhibitor, on the other hand, competes with the substrate for binding to the active site of the enzyme, blocking its function.

What is the difference between a competitive inhibitor and an allosteric inhibitor in terms of their mechanisms of action on enzymes?
A competitive inhibitor competes with the substrate for the active site of an enzyme, blocking its function. An allosteric inhibitor binds to a different site on the enzyme, causing a conformational change that reduces the enzyme's activity.
What is the difference between an allosteric inhibitor and a noncompetitive inhibitor in terms of their mechanisms of action on enzyme activity?
An allosteric inhibitor binds to a site on the enzyme that is different from the active site, causing a change in the enzyme's shape and reducing its activity. A noncompetitive inhibitor binds to either the enzyme or the enzyme-substrate complex, also reducing enzyme activity but without directly competing with the substrate for the active site.
What is the difference between a noncompetitive inhibitor and an allosteric inhibitor in enzyme regulation?
A noncompetitive inhibitor binds to an enzyme at a site other than the active site, while an allosteric inhibitor binds to a different site on the enzyme, causing a change in the enzyme's shape and reducing its activity.
What are the key differences between non-competitive inhibition and allosteric inhibition in enzyme regulation?
Non-competitive inhibition occurs when an inhibitor binds to an enzyme at a site other than the active site, changing the enzyme's shape and reducing its activity. Allosteric inhibition involves an inhibitor binding to a specific regulatory site on the enzyme, causing a conformational change that decreases enzyme activity. The key difference is that non-competitive inhibition does not compete with the substrate for the active site, while allosteric inhibition involves binding to a separate site on the enzyme.
How do allosteric regulation and competitive inhibition compare?
A competitive inhibition and allosteric regulation both involves an inhibitor molecule binding to the enzyme at a different area. The difference between the two is that allosteric inhibitors are modulator molecules which bind somewhere besides the catalytic activity.

What is allosteric inhibitor of glutamate dehydrogenase?
GTP
Why does adding additional substrate overcome competitive but not noncompetitive inhibition?
A competitive inhibitor competes with the substrate to bind to the active site while a noncompetitive inhibitor binds to an allosteric site of the enzyme (one other than the active site). Thus no amount of substrate can overcome or in a sense interfere with the inhibitors binding to an allosteric site.

A competitive inhibition and allosteric regulation both involves an inhibitor molecule binding to the enzyme at a different area. The difference between the two is that allosteric inhibitors are modulator molecules which bind somewhere besides the catalytic activity.
How does an allosteric inhibitor function to regulate enzyme activity?
An allosteric inhibitor regulates enzyme activity by binding to a site on the enzyme that is different from the active site. This binding changes the enzyme's shape, making it less effective at catalyzing reactions.
How would one overcome the effects of a competitive inhibitor on enzyme activity in the biochemical regulation of metabolic pathways?
One way to overcome the effects of a competitive inhibitor on enzyme activity is to increase the substrate concentration. By increasing the substrate concentration, you can outcompete the inhibitor for binding to the enzyme's active site. Another strategy is to use allosteric regulators that can bind to a separate site on the enzyme and change its conformation, potentially reducing the inhibitor's binding affinity.
What are the two different types of inhibition?
Increasing the temperature excessively - if an enzyme is heated too much (usually around 40°C) the enzyme will become denatured. This will prevent it from working permanently. Decreasing the temperature - decreases enzyme activity Enzyme inhibitors - heavy metals poison enzymes by binding to the active site, preventing the enzyme from binding to the substrate molecule.
