Question

which site of an enzyme is called an allosteric site?

Answer 1

Enzyme Activity: Allosteric Sites. ... These molecules bind the allosteric site and change the confirmation, or shape, of the enzyme. Molecules that turn off enzymes are called allosteric inhibitors. Allosteric inhibitors change how the active site is shaped and prevents it from binding, or attaching, to the substrate.


Hope this will help you

Answer 2

Answer :-

Some enzymes possess a receptor site on their bodies. Such sites are termed as "Allosteric sites".

Extra Information :-

~~~~~~~~~~~~~~~~~~~~~~~~

• The enzymes which sport Allosteric sites, are known as "Allosteric Enzymes" ( Eg - Glucokinase, Phosphofructokinase).

• The word "Allosteric" means "Another space".

• An Allosteric enzyme has an active site along with two types of allosteric sites.

• According to the scientists - "Monod" (1965) and "Wyman" (1965), an allosteric enzyme consists of two identical sub-units.

• The sub-units of allosteric enzymes consist of one active site each.

• Substances which bring about changes in the allosteric sites, are termed as "Allosteric regulators" or "Modulators".

• The two types of Modulators are termed as "Allosteric activators" and "Allosteric inhibitors".
