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.
How can you determine experimentally whether or not a substance is present in ionic or molecular form when in aqueous solution?
If the solution will conduct electricity it is ionic. Solutions made from molecules do not conduct electricity.
How do you use inhibitor in a sentence?
An enzyme inhibitor is a substance that binds to an enzyme and decreases the enzyme's activity.
What is the difference between a catalyst and an inhibitor?
Catalyst: a substance which promote and help a chemical reaction. Inhibitor: a substance which greatly reduces the rate of a chemical reaction.
How is competitive inhibition different from competitive inhibition?
Competitive Inhibition is a substance that binds to the active site in place of the substance while Non-competitive Inhibition is a substance that binds to a location remote from the active site. (:
How is competitive inhibition different from non competitive inhibition?
Competitive Inhibition is a substance that binds to the active site in place of the substance while Non-competitive Inhibition is a substance that binds to a location remote from the active site. (:
What is a substance that slows down or stops a chemical reaction?
an inhibitor
What do you call a substance speeding up a chemical process?
if at the end of the chemical THAT substance is unchanged .That substance is a catalyst. If it slows donw the reaction, it is called an inhibitor.
A substance that delays decomposition is called an what?
In chemical term such a substance is aNegative catalyst or inhibitor in food industry it is known as preservative.
What is a substance that interferes with a catalyst?
An inhibitor is a substance that interferes with a catalyst. Inhibitors also interfere with other biologic activity such as growth.
What is inhibitor mean?
Inhibitor may refer to a molecule or a protein or any substance that inhibits a process or a particular other molecules (mostly proteins). Tetracycline can inhibit the protein synthesisin bacteria. Thus we are taking antibiotics as an inhibitor to get cured of bacterial infection.
What is a meaning of inhibit?
To check; to hold back; to restrain; to hinder., To forbid; to prohibit; to interdict.
