Which one of the following statements is correct, with reference to enzymes?
Apoenzyme = Holoenzyme + Coenzyme
Holoenzyme = Apoenzyme + Coenzyme
Coenzyme = Apoenzyme + Holoenzyme
Holoenzyme = Coenzyme + Cofactor
Co-enzymes as cofactor -
A cofactor is an organic compound and their association with the apoenzyme is only transient, usually occurs during the course of catalysis.
- wherein
Eg: NAD and NADP.
Coenzymes are transiently associated with apoenzyme, forming a holoenzyme
Option 1)
Apoenzyme = Holoenzyme + Coenzyme
This is incorrect option
Option 2)
Holoenzyme = Apoenzyme + Coenzyme
This is correct option
Option 3)
Coenzyme = Apoenzyme + Holoenzyme
This is incorrect option
Option 4)
Holoenzyme = Coenzyme + Cofactor
This is incorrect option
