Which best describe an enzyme?
it is globular protein
act as biological catalyst
its monomer is amino acid
speed up a chemical reaction
Enzymes possess active site, so that
its shape is globular
it can lowering the activation energy
substrate can bind
chemical reaction is faster
Which of the following match with the characteristics of enzyme that the bonds are broken down and cause enzyme is not function anymore
will denature in high pH and temperature
enzyme is highly specific
will denature in extreme pH & very high temperature
enzyme is reusable
Only protease can catalyses the breakdown of protein. This shows that enzyme
is a biological catalyst
is highly specific in action
able to speed up chemical reaction
may catalyses reversibly
Enzyme that catalyses the transfer of functional group of atoms from one molecule to another. This enzyme is

Transferases
Oxidoreductase
Lyases
- Amylase
- Lipase
- Peptidase/Protease
These enzymes are example of
Ligases
Lyases
Transferase
Hydrolases
Enzymes in group Isomerases catalyse
the rearrangement of atoms
the transfer of functional group of atoms
the breaking of chemical bond
the formation of bonds
