Are all enzymes protein based?
Ribozyme.
With the exception of ribozymes, all enzymes are protein-based.
Define enzymes.
Enzymes can be defined as biological polymers that catalyze biochemical reactions.
What is the induced fit theory? .
Beverages
Alcoholic beverages generated by fermentation vary a lot based on many factors.
Based on the type of the plant’s product, which is to be used and the type of enzyme applied, the fermented product varies.
For example, grapes, honey, hops, wheat, cassava roots, and potatoes depending upon the materials available.
Beer, wines and other drinks are prod.
Food Products
Bread can be considered as the finest example of fermentation in our everyday life.
A small proportion of yeast and sugar is mixed with the batter for making bread.
Then one can observe that the bread gets puffed up as a result of fermentation of the sugar by the enzyme action in yeast, which leads to the formation of carbon dioxide gas.

Isomerases
They catalyze the formation of an isomer of a compound.
Example: phosphoglucomutase catalyzes the conversion of glucose-1-phosphate to glucose-6-phosphate (phosphate group is transferred from one to another position in the same compound) in glycogenolysis (glycogen is converted to glucose for energy to be released quickly).
Ligases
Ligases catalyze the association of two molecules.
For example, DNA ligase catalyzes the joining of two fragments of DNA by forming a phosphodiester bond.
Lyases
These catalyze the breakage of bonds without catalysis, e.g. aldolase (an enzyme in glycolysis) catalyzes the splitting of fructose-1, 6-bisphosphate to glyceraldehyde-3-phosphate and dihydroxyacetone phosphate.
Oxidoreductases
These catalyze oxidation and reduction reactions, e.g. pyruvate dehydrogenase, catalysing the oxidation of pyruvate to acetyl coenzyme A.
Transferases
These catalyze transferring of the chemical group from one to another compound.
An example is a transaminase, which transfers an amino group from one molecule to another.
What are enzymes & how do they work?
Enzymes are catalysts that drive reaction rates forward.
Most catalysts, but not all, are made up of amino acid chains called proteins that accelerate the rate of reactions in chemical systems.
The functionality of a catalyst depends on how the proteins are folded, what they bind to, and what they react with.
What are the properties of enzymes?
Properties of enzymes Enzymes are the complex protein molecules, often called biocatalysts, which are produced by living cells.
They are highly specific both in the reactions that they catalyze and in their choice of reactants, which are known as substrates.
Why do enzymes have a unique chemical environment?
Enzymes have an active site that provides a unique chemical environment, made up of certain amino acid R groups (residues).
This unique environment is well-suited to convert particular chemical reactants for that enzyme, called substrates, into unstable intermediates called transition states.
Flavorant food additive
Enzyme-modified cheese (EMC) is a concentrated cheese flavour ingredient that is produced from cheese by treatment with enzymes such as proteases, lipases and esterases.
These enzymes accelerate and intensify the ripening of cheese, which is normally done with enzymes released by an microbial culture.
They may be added to during cheesemaking, after the cheese curds have been pressed, or even after the cheese has been naturally aged.
EMCs were first made in the 1970s.
A restriction enzyme or restriction endonuclease is a special type of biological macromolecule that functions as part of the immune system in bacteria.
One special kind of restriction enzymes is the class of homing endonucleases, these being present in all three domains of life, although their function seems to be very different from one domain to another.
