Which one of the following statements is correct, with reference to enzymes? A. Apoenzyme= Holoenzyme+Coenzyme B. Holoenzyme= Apoenzyme+Coenzyme C. Coenzyme=Apoenzyme+Holoenzyme D. Holoenzyme=Coenzyme+Cofactor
Option B Holoenzyme is the active form of the enzyme. It is made of 2 components called the apoenzyme and coenzyme. A cofactor can also be called 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.
