Why is it easier for the fourth oxygen molecule to bind to hemoglobin?
It is not the fourth one specifically that binds easier, O2 is a positive allosteric effector (activator) of Haemoglobin and the binding of O2 facilitates further binding of O2. I'm not sure why this is though.
What is Decreased ATP production?
Cell respiration is actually a negative feedback system. If too many ATPs are produced, they will go back to the beginning of the reaction (glycolysis) and act as allosteric inhibitors to phosphofructokinase. Citrate works in the same way to inhibit the phosphofructokinase present in glycolysis and in the Krebs Cycle. However, the rate of cell respiration can increase with increasing levels of ADP, which acts as an allosteric activator.
How allosteric enzymes differ non allosteric?
Allosteric enzymes have the ability to change their conformational ensemble after binding. This changes their affinity at a different ligand binding site.
What statement is characteristic of allosteric effectors?
Allosteric effectors may not resemble the enzyme's substrates.
What is allosteric inhibitor of glutamate dehydrogenase?
GTP
What happens during allosteric inhibition?
Allosteric (noncompetitive) inhibition results from a change in the shape of the active site when an inhibitor binds to an allosteric site. When this occurs the substrate cannot bind to its active site due to the fact that the active site has changed shape and the substrate no longer fits. Allosteric activation results when the binding of an activator molecule to an allosteric site causes a change in the active site that makes it capable of binding substrate.

What is the difference between an allosteric enzyme and a non-allosteric enzyme?
alloesterinc enzymes have 2 or more binding sites which can bind the same or different molecules. When a molecule bind one of the sites the other site changes conformation and gets a higher affinity for a ligand. this is allostric coorporation. alloestric sites can also regulate binding of a ligand by preventing binding if they are occupied. this is alloesteric regulation. allo means "other" sterio means "site" so allosteric means "other site". a regular enzyme has one or more binding sites but they are independent of each other i.e. binding of a ligand to one site does not increase or decrease affinity of binding in the other site.

What is an activator in ICT?
it is the activator device
What is the allosteric inhibitor?
The inhibitor which binds or attached with the allosteric site of enzyme k/n as A.I ... BY "NAHEED KHATTI "
What blocks enzyme activity by binding to allosteric site of an enzyme causing the enzyme's active site to change shape?
An allosteric inhibitor stops enzyme activity by binding to an allosteric site and causing the conformation of the enzyme to change.
What is the difference between inhibitor and activator?
difference between activator and inhibitor
Some enzymatic regulation is allosteric?
yes
