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
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.
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 are the two different types of inhibition?
Increasing the temperature excessively - if an enzyme is heated too much (usually around 40°C) the enzyme will become denatured. This will prevent it from working permanently. Decreasing the temperature - decreases enzyme activity Enzyme inhibitors - heavy metals poison enzymes by binding to the active site, preventing the enzyme from binding to the substrate molecule.
Give examples of inhibitors?
An example of an inhibitor is a preservative. Preservatives are added to foods to slow down the growth of bacteria and fungi. The preservatives prevent bacteria and fungi from producing substances that can spoil food. Some antibiotics are examples of inhibitors also. For example, penicillin prevents certain kinds of bacteria from making a cell wall .So, the bacteria die.
Increasing the substrate concentration in an enzymatic reaction could overcome what?
competitive inhibition
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 the type of enzyme inhibition in which the Km changes but the Vmax does not?
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.
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.
What is a molecule occupying the active site of an enzyme so that there can be no normal enzyme-substrate complex formed called?
It is called competitive Inhibition.
