Q. The proteinaceous molecule that joins a non-proteinaceous prosthetic group to form a functional enzyme is called
A) Co-factor
B) Apoenzyme
C) Holoenzyme
D) Isoenzyme
Explanation
The enzymes which work only in the presence of cofactors are known as apoenzymes. A working combination of an apoenzyme and cofactor (mineral ion, prosthetic group or coenzyme) is called enzyme system or holoenzyme. Apoenzyme + Mineral ion/Prosthetic/ Coenzyme group $\rightarrow$ Enzyme system or holoenzyme
