A competitive inhibitor.
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.
The vmax stays the same as the competitive reversible inhibitor does not affect catalysis in the enzyme-substrate.
a substrate =================================== or an "interacting molecule".
Repressors bind to the silencers in the DNA to block the RNA polymerase from binding to the promoter of the gene to reduce gene expression, not really binding to enzymes active sites I think what you meant was "what does an inhibitor do to the enzymes active site"? In which case, it depends on the type of inhibitor. A competitive inhibitor has a structure similar to the substrate, hence would bind to the active site as well, competing with the substrate for the enzyme active sites, decreasing enzymatic activity. A non-competitive inhibitor binds to the allosteric site of the enzyme, causing a structural change in the enzyme active site shape. Hence the enzyme would not be able to bind to the original substrate, so enzymatic activity comes to a halt for the enzymes that are bound by the non-competitive inhibitors
it allows an inhibitor to block the active site of the enzyme

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.
because the competitive inhibitor stops the regular substrate from joining the enzyme. Its takes its place in the enzyme.
The vmax stays the same as the competitive reversible inhibitor does not affect catalysis in the enzyme-substrate.
both substrate and competitive inhibitor
This would be a competitive inhibitor. It can be a structural analog of the substrate. This type of inhibition can be out competed by adding more substrate. A competitive inhibitor increases the Km of the enzyme.
Add more substrate; it will outcompete the inhibitor and increase the reaction rate. Competitive inhibition can be overcome by adding more substrate to outcompete the inhibitor. Many drugs used to treat different medical conditions, including hypertension, are competitive inhibitors. It is fairly easy to make a molecule that is similar in structure to a particular substrate because the known enzyme's shape can be used as a model of what the molecule needs to look like. It is more difficult to make a noncompetitive inhibitor because it is less obvious what the noncompetitive inhibitor's shape and structure should be.
The inhibitor.
No change in enzyme activity would be observed.
a substrate =================================== or an "interacting molecule".
Increase the amount of substrate for the enzyme.
