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
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.
Is penicillin an competitive inhibitor?
yes it is
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 is an example of a penicillin mixed with a beta-lactamase inhibitor?
The drug Augmentin, for example, contains a combination of amoxicillin and a betalactamase inhibitor, clavulanic acid.
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.
