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 penicillin an competitive inhibitor?
yes it is
Is penicillin a non-competitive inhibitor?
no
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 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.
What is the purpose of using malonic acid in this experiment?
it is a competitive inhibitor
What is is called when something competes with the enzymes on its subtrate?
A competitive inhibitor.
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.
Do noncompetitive inhibitors bind to the active site?
A non-competitive inhibitor
What statement best describes the function of a competitive inhibitor in an enzyme-catalyzed reaction?
Competitive inhibitor is a substance that competes directly with a normal substrate for an enzymatic-binding site of an enzyme. Such an inhibitor usually resembles the substrate to the extent that it specifically binds to the active site of the enzyme but differs from it so as to be unreactive and therefore there will be no catalytic reaction. Some examples are: methotrexate that is competitive inhibitor of dihydrofolate reductase, and malonate which structurally resembles succinate (that is converted to fumarate by succinate dehydrogenase during the citric acid cycle) but cannot be dehydrogenated.
