How is competitive inhibition different from non competitive inhibition?

∙ 11y ago
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 the type of inhibition of invertase by urea?
Urea is a non-competitive inhibitor which means that the Vmax will decrease and the Km will remain unchanged during the process.
What is Difference between uncompetitive and non competitive enzyme inhibition?
I believe non competitive antagonists bind to an allosteric site that prevents the enzyme from binding substrate whereas uncompetitive binds and stabilizes the ES complex which slows down the reaction.
What happens if an inhibitor is irreversible?
Irreversible inhibition refers to the inactivation of an enzyme by a tightly, typically covalent, bound inhibitor. The kinetics for irreversible inhibition do not follow competitive or non-competitive kinetics.
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.
Is copper sulfate a competitive or noncompetitive inhibitor?
Non-Competitive Inhibitor
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. (:
What are the difference of competitive and non competitive inhibition...want the answer in term Km and Vmax?
Competitive inhibition: Vmax remains the same and Km Changes Non-competitive (pure): Vmax changes and Km remain the same
Increasing the substrate concentration in an enzymatic reaction could overcome what?
competitive inhibition

What is Difference between uncompetitive and non competitive enzyme inhibition?
I believe non competitive antagonists bind to an allosteric site that prevents the enzyme from binding substrate whereas uncompetitive binds and stabilizes the ES complex which slows down the reaction.
What are the types of feedback inhibition?
There are two main types of feedback inhibition: competitive inhibition, where an inhibitor competes with the substrate for the active site of an enzyme; and non-competitive inhibition, where an inhibitor binds to a site on the enzyme other than the active site, altering the enzyme's shape and reducing its activity.
How do allosteric regulation and competitive inhibition compare?
A competitive inhibition and allosteric regulation both involves an inhibitor molecule binding to the enzyme at a different area. The difference between the two is that allosteric inhibitors are modulator molecules which bind somewhere besides the catalytic activity.
In what two ways could morphine inhibit the the enzyme that breaks down acetecholine?
Enzyme-activity studies on acetylcholinesterase (AChE), the enzyme that is responsible for hydrolyzing acetylcholine (ACh), in the presence of opioids date back to the 1940s.AChE inhibition by opioids has been suggested to be partly competitive and partly non-competitive(1, 2). Competitive inhibition would imply that that opiods compete with ACh for AChE, while non-competitive inhibition could mean that opioids bind to non-ACh binding regions on AChE and inactivate the part that hydrolyzes ACh.Because AChE can still hydrolyse ACh in the presence of opioids the inhibition is only partial. This would make opioids partial competitive and partial non-competitive antagonists of AChE. Its unlikely that inhibition is biologically meaningful, however (3).1.

What is the type of enzyme inhibition in which the Km changes but the Vmax does not?
competitive
How does the induced fit model help to explain non-competitive inhibition?
The induced fit model is the theory that instead of enzymes and substrates fitting exactly together, as in the lock and key model, the enzyme changes shape around the substrate to bind with it. Non-competitive inhibition is where the inhibitor does not fit into the active site, but into another site on the enzyme instead, which changes the shape of the active site.
What happens when a protein is inhibited?
When a enzyme is inhibited (many proteins are enzymes), it just means that the enzyme will be reduced in its ability to catalyze a reaction. There are a few types of Inhibition like Competitive Inhibition, Noncompetitive Inhibition, and Irreversible Inhibition.
