If an enzyme has two or more subunits, a substrate molecule causing induced fit in one subunit can trigger the same favorable conformational change in all the other subunits of the enzyme. Essentially, enzyme cooperativity is a mechanism of amplification regarding the response of enzymes to substrates: One substrate molecule primes an enzyme to accept additional substrate molecules more readily.

What is mnemonical enzyme?
Allosteric enzymes are mostly polymeric in nature i.e. they are made up of several subunits. These enzymes exhibit cooperativity i.e. binding of a ligand to the active site alters (increase or decrease) the binding affinity of the ligand on other sites. Some monomeric enzymes also exhibit cooperativity. Those monomeric enzymes which exhibit cooperativity are called mnemonical enzymes. Hexokinase D (an isoenzyme of hexokinase) is one such example.
What is the Difference between enzyme and regulatory enzyme?
An enzyme is one kind of protein that can catalyze a specific reaction whereas a regulatory enzyme is the enzyme which can regulate a series of reaction which undergo in the living organism. So we can say every enzyme is not a regulatory one but the regulatory enzymes are obviously a special kind of enzyme.
What kind of molecule is an enzyme-?
The type of molecule that is an enzyme is a protein molecule.
How is a catalyst like platinum different from an enzyme?
Catalysts are compounds that change the speed of chemical reactions. An enzyme is a protein and also a catalyst. So an enzyme can be a catalyst, but a catalyst can't be an enzyme.
What does the shape of an enzyme have to do with how well the enzyme works?
The shape allows the enzyme to carry out specific chemical reactions.

Distinguish between allosteric activation and cooperativity?
cooperativity is an interaction of the subunits of a protein whereby a conformational change in one subunit is transmitted to all others. allosteric regulation is when an activation molecule bonds to an active site where the subunits join.
What is an example of cooperativity?
Cooperation is an important structural tool for groups. An example of cooperation is a group of people working together to build a house.
Why symmetry model can only explain positive homotropic cooperativity?
Homotropic molecules have chemically identical H's. As in the molecule can be cut in half and the hydrogens are all of the same molecular strength.
What can you do to regain the activity of the enzyme?
The enzyme is inactive at this point. New enzyme must be added to regain enzyme activity
What to enzymes do in an enzyme-substrate?
in an enzyme-substrate complex, the enzyme acts on the substrate .
Does enzyme has proteins?
An enzyme is a protein
What is the active site for an enzyme?
The place where the substrate and the enzyme meet to allow the enzyme to function.
What is an angiotensin converting enzyme?
An angiotensin converting enzyme is an enzyme which catalyzes the creation of angiotensin.
What enzyme is responsible for fat digestion?
the lipase enzyme :)
The binding together of an enzyme and a substrate forms a what?
enzyme-substrate complex
