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.

∙ 11y agoCompetitive inhibitors resemble substrate and it occupies active site and in this way inhibits enzyme.
Noncompetitive inhibitor occupies site other than the active site and does not resemble substrate.

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 kind of inhibitor is cyanide?
Noncompetitive inhibitor.
Is lactose a noncompetitive inhibitor?
yes
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.
Do noncompetitive inhibitors bind to the active site?
A 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.
When the noncompetitive inhibitor is bonded to the enzyme?
The shape of the active site is distorted.
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.
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 kind of inhibitor is cyanide?
Noncompetitive inhibitor.
Is lactose a noncompetitive inhibitor?
yes
Is copper sulfate a competitive or noncompetitive inhibitor?
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.
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.
Do noncompetitive inhibitors bind to the active site?
A non-competitive inhibitor
How do you use inhibitor in a sentence?
An enzyme inhibitor is a substance that binds to an enzyme and decreases the enzyme's activity.
Competitive and noncompetitive enzyme inhibitors differ with respect to?
the precise location on the enzyme to which they bind
