|
Apoenzyme |
Coenzyme
|
|
It is the protein part of the
holoenzyme or conjugate enzyme. |
Coenzyme is the nonprotein organic
group that gets attached to the apoenzyme to form a holoenzyme or conjugate

It is small in size |
|
An apoenzyme is specific for an
enzyme. |
A coenzyme can function as a cofactor
for a number of enzymes carrying out that particular type of reaction. |
|
It takes part only in the catalytic activity of the enzyme. |
It helps in removing a product of
chemical reaction besides bringing contact between the substrate and the
enzyme. |
|
Apoenzyme does not help in group
transfer. |
Coenzyme takes part in group transfer. |
|
Apoenzyme is thermolabile. |
Coenzyme is heat stable. |
