Question

Identify the correct statement? *
A. Apoenzyme= Holoenzyme+ Coenzyme
B. Holoenzyme = Apoenzyme+ Coenzyme
C. Coenzyme= Apoenzyme+ Holoenzyme
D. Holoenzyme= Coenzyme+ Cofactor​

Answer 1

Holoenzyme is the active form of the enzyme. It is made of 2 components called the apoenzyme and coenzyme. A cofactor can also be a called as a coenzyme if it is an organic molecule. The apoprotein itself is inactive. On binding with the cofactor, it gets activated resulting in the formation of a holoenzyme that is functional. Thus the correct answer is option B.
