What kind of inhibitor is cyanide?
Noncompetitive inhibitor.
Do noncompetitive inhibitors bind to the active site?
A non-competitive inhibitor
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.
What would be the likely outcome if you increased the concentration of substrate for an enzyme in the presence of a noncompetitive inhibitor?
No change in enzyme activity would be observed.
What is non-competitive enzyme inhibitor?
Competitive inhibition is where a inhibitor has a structural similarities of a substrate. Due this the inhibitor binds to the active site of the enzyme,where normally substrate binds. This binding of the inhibitor to the enzyme forms a EI complex instead of ES complex and thus inhibiting the catalytic activity of an enzyme. Non competitive inhibition is when inhibitor possessing same structure of substrate binds to the site other than the active site of an enzyme. The substrate binds to the active site of an enzyme. This binding of the inhibitor to the site other than an active site disturbs the normal structure of an enzyme. Thereby, lowering the catalytic activity of an enzyme.
What kind of inhibitor is cyanide?
Noncompetitive inhibitor.
Is copper sulfate a competitive or noncompetitive inhibitor?
Non-Competitive Inhibitor
A noncompetitive inhibitor has a structure that?
A noncompetitive inhibitor has a structure that does not resemble the substrate structure. A compound that binds to the surface of an enzyme, and changes its shape so that a substrate cannot enter the active site is called a noncompetitive inhibitor.
Do noncompetitive inhibitors bind to the active site?
A non-competitive inhibitor
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.
When the noncompetitive inhibitor is bonded to the enzyme?
The shape of the active site is distorted.
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.
What would be the likely outcome if you increased the concentration of substrate for an enzyme in the presence of a noncompetitive inhibitor?
No change in enzyme activity would be observed.
What can you do to speed the reaction up again?
You can speed up a reaction by increasing the temperature, concentration of reactants, or using a catalyst. These factors can provide more energy to the reacting molecules, increase their frequency of collisions, or lower the activation energy barrier, respectively.
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.

Competitive inhibition is where a inhibitor has a structural similarities of a substrate. Due this the inhibitor binds to the active site of the enzyme,where normally substrate binds. This binding of the inhibitor to the enzyme forms a EI complex instead of ES complex and thus inhibiting the catalytic activity of an enzyme.

This binding of the inhibitor to the site other than an active site disturbs the normal structure of an enzyme. Thereby, lowering the catalytic activity of an enzyme.
How does the non-competitive inhibitor decrease the rate of an enzyme reaction?
Noncompetitive inhibitors decrease the rate of an enzyme reaction by bonding to an enzyme somewhere other than the active site, deforming it and permanently disabling the enzyme, so that enzyme can never function again, so the rate of reaction decreases.
