Answer: CHEMISTRY OF ENZYMES:
Enzymes are ‘biological catalysts’. They are made up of globular proteins and they enhance the
speed of biochemical reactions. They can be regenerated and used in the same reaction again
and again without being used in it. They lower the ‘activation energy’ required for a reaction.
TWO TYPES OF ENZYMES:
There are two types of enzymes:
1. Catabolic Enzymes
2. Anabolic Enzymes
1. Catabolic Enzymes:
“The enzymes that break down large particles of a substrate to convert it to small molecules for
usage purposes are called catabolic enzymes.
2. Anabolic Enzymes:
“The enzymes that combine small molecules to make up a large molecule required for a reaction
are called anabolic enzymes.”
CHEMISTRY OF ENZYMES:
Each enzyme has an ‘active site’ and a ‘binding site’.
An active site has is where a substrate gets attached and can be converted to a product
through enzyme-substrate complex.
An active site is also called ‘catalytic site’ where the catalysis takes place and it can
change its shape according to the substrate.
A binding site is a site where a ligand (an ion that donates a pair of electrons to central
metal atom ) can gets attached.
The rate of the reaction catalyzed by enzymes also depends upon ‘cofactors, coenzymes
and concentration of enzymes and substrates.”
APOENZYMES:
“Apo-enzymes are formed by when a co-factor gets attached to it to make it active. Otherwise it
is an inactive part of an enzyme. They make an enzyme specific for its substrate.
