What inhibitor has a structure that is so similar to the substrate that it can bond to the enzyme just like the substrate?

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?
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.
What happens to the vmax when a competitive reversible inhibitor is added to an enzyme?
The vmax stays the same as the competitive reversible inhibitor does not affect catalysis in the enzyme-substrate.
Molecule that binds to an enzyme?
a substrate =================================== or an "interacting molecule".
What does a repressor do in the enzymes active site?
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
How does the three-dimensional structure of trypsin affect its action as an enzyme?
it allows an inhibitor to block the active site of the enzyme

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.
Why would the reaction of a normal rate of an enzyme slow down and its substrate slow down when a competitive inhibitor is present?
because the competitive inhibitor stops the regular substrate from joining the enzyme. Its takes its place in the enzyme.
What happens to the vmax when a competitive reversible inhibitor is added to an enzyme?
The vmax stays the same as the competitive reversible inhibitor does not affect catalysis in the enzyme-substrate.
What is the name of the reactant that bind to an enzyme's active site?
both substrate and competitive inhibitor
What inhibitor binds into the active site of an enzyme not allowing the subrtate to bind?
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.
What is it called when a substance other than the intended substrate binds with the enzyme there by blocking the enzyme fall catalyzing the reaction?
The inhibitor.
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.

a substrate =================================== or an "interacting molecule".
How would one overcome the effects of a competitive inhibitor on enzyme activity in the biochemical regulation of metabolic pathways?
Increase the amount of substrate for the enzyme.

Differences between succinate and succinate malonate?
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.
