What inhibitor has a structure that is so similar to the substrate that it can bond to the enzyme just like the substrate?
Competitive inhibitor. It is termed to be an analogue. It is also known to sometimes act as a "catalytic poison".
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.
Inhibitors that decrease an enzymes activity by binding to the active site?
I would just call it an inhibitor. An inhibitor may be a small molecule,such as a metal or it may be a protein.
What is a meaning of inhibit?
To check; to hold back; to restrain; to hinder., To forbid; to prohibit; to interdict.
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
Is penicillin a non-competitive inhibitor?
no
Is copper sulfate a competitive or noncompetitive inhibitor?
Non-Competitive Inhibitor
What happens the reaction time with a competitive inhibitor?
with a competitive inhibitor the reaction time proceeds slowly.
Is PTU a competitive inhibitor?
non-competitive
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.

Competitive inhibitor. It is termed to be an analogue. It is also known to sometimes act as a "catalytic poison".
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 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 is is called when something competes with the enzymes on its subtrate?
A competitive inhibitor.
What is the purpose of using malonic acid in this experiment?
it is a competitive inhibitor

Do noncompetitive inhibitors bind to the active site?
A non-competitive inhibitor
