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.
both substrate and competitive inhibitor
because the competitive inhibitor stops the regular substrate from joining the enzyme. Its takes its place in the enzyme.
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.
Its one of these answers, if that narrows it down.... a. product. b. inhibitor. c. coenzyme. d. substrate.
Competitive inhibitor. It is termed to be an analogue. It is also known to sometimes act as a "catalytic poison".
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.
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.

A 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.
both substrate and competitive inhibitor
The vmax stays the same as the competitive reversible inhibitor does not affect catalysis in the enzyme-substrate.
because the competitive inhibitor stops the regular substrate from joining the enzyme. Its takes its place in the enzyme.
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

Malonate is a competitive inhibitor preventing the substrate succinate from binding to the enzyme. The structure of succinate is comparable to that of malonate but for the ability for malonate to bind to an enzyme but then cannot further act on it creating a nonproductive complex.
