The Catalytically Active Complex of an Apoenzyme and Its Prosthetic

Question

The catalytically active complex of an apoenzyme and its prosthetic group is referred to a(n) ____.
A) catalytic duo
B) holoenzyme
C) prosthetic enzyme
D) dimeric enzyme
E) none of the above

Accepted Answer

A holoenzyme is formed when an apoenzyme (an enzyme without its required cofactor or prosthetic group) is combined with its corresponding cofactor or prosthetic group. The resulting complex is the catalytically active form of the enzyme. Therefore, the answer is B, holoenzyme.
