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.
Which type of control agent exerts noncompetitive inhibition?
A noncompetitive inhibitor binds to an allosteric site on the enzyme, causing a conformational change that reduces the enzyme's activity without competing with the substrate for the active site. This type of control agent is called a noncompetitive inhibitor.
Does Allosteric regulation depends on inhibitors binding to the active site of enzymes?
No, allosteric regulation involves molecules binding to a site other than the active site (allosteric site) to either activate or inhibit enzyme activity. This type of regulation can involve activators or inhibitors that induce conformational changes in the enzyme, affecting its activity.
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 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.

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.

Where does a noncompetitive inhibitor bind in relation to the enzyme's active site?
A noncompetitive inhibitor binds to a site on the enzyme that is not the active site.
What is the allosteric inhibitor?
The inhibitor which binds or attached with the allosteric site of enzyme k/n as A.I ... BY "NAHEED KHATTI "
Is lactose a noncompetitive inhibitor?
No, lactose is not a noncompetitive inhibitor. Lactose is a sugar found in milk that can act as an inducer for the lactose operon in bacteria, but it does not act as an inhibitor in enzyme kinetics.
Why will increasing the substrate concentration not decrease the effect of a non competitive inhibitor?
Because you will still have the same number of enzymes inhibited. For example, you have 20 enzymes and 10 non-competitive inhibitors. Regardless of substrate concentration, at any one time, there will only be 10 enzymes available to accept a substrate. Increasing the substrate concentration does not affect this.
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.
