What is the cite when other substrates bind to enzymes to alter activity?
The competitive inhibitors bind in the active site while noncompetitive inhibitors bind at an allosteric site, which is located somewhere else on the enzyme other than the active site.
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.
Can enzyme activity be affected by salinity and inhibitors?
Yes, both salinity and inhibitors can affect enzyme activity. There are two types of inhibitors, non-competitive and competitive inhibitors that will either bind to the allosteric or active site respectively.
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.
What is the role of enzymes in biological systems?
Enzymes are regulated with the use of Competitive Inhibitors and Noncompetitive Inhibitors. Basicly every enzyme has an active site where the substrate binds to and what an the first kind of inhibtor does is that it blocks the substrate from joining with the enzyme by attaching to the enzyme's active site. The other kind of inhibitor joins with the enzyme at another place not the active site. This makes the enzyme change shape so it cannot fit the substrate or it somehow makes the enzyme unable to catalize the reaction.~Draco

How do competitive and noncompetitive inhibitions differ?
A competitive inhibitor often binds to an enzyme's active site. Noncompetitive inhibitors usually bind to a different site on the enzyme.
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.
Does Allosteric regulation depends on inhibitors binding to the active site of enzymes?
Of course. That is the meaning of ' noncompetitive inhibitor. ' It does not compete with the substrate at the active site but inhibits enzyme activity at the allosteric ( other site ) site.
Substrate molecules bind to enzymes where?
The bind in the active site.
Where do reactants bind to the enzyme?
They bind in the active site.
Can enzyme activity be affected by salinity and inhibitors?
Yes, both salinity and inhibitors can affect enzyme activity. There are two types of inhibitors, non-competitive and competitive inhibitors that will either bind to the allosteric or active site respectively.
Inhibitors that decrease an enzymes activity by binding to the active site?
I would just call it an inhibitor. An inhibitor may be a small molecule,such as a metal or it may be a protein.
Inhibitors of enzymes-catalyzed reactions act by?
Different Enzymes inhibit in different ways. Some are structural analogue of substrate and they compete the substrate in binding to the enzyme. Some inhibitors bind in the active site and prevent the binding of the enzyme. Some enzymes doesn't bind the active site but they change the active site properties that prevent the efficient binding of the substrate. some time substrate in large quantity may inhibit the enzyme, while other times the product formed may do so.

Difference between reversible and irreversible inhibitors?
Enzyme inhibitors are molecules that bind to enzymes and decrease their activity. The binding of an inhibitor can stop a substrate from entering the enzyme's active site and/or hinder the enzyme from catalyzing its reaction. Inhibitor binding is either reversible or irreversible. Irreversible inhibitors usually react with the enzyme and change it chemically. These inhibitors modify key amino acid residues needed for enzymatic activity. In contrast, reversible inhibitors bind non-covalently and different types of inhibition are produced depending on whether these inhibitors bind the enzyme, the enzyme-substrate complex, or both.
