What is the function of cofactors in enzymes?
What is the function of cofactors in enzymes?
Options
- ATo make the enzyme catalytically active.
- BTo break down hydrogen peroxide.
- CTo tightly bind to the apoenzyme.
- DTo catalyze the breakdown of water.
Correct answer
A. To make the enzyme catalytically active.
Step-by-step solution
Enzymes are composed of one or several polypeptide chains. However, there are a number of cases in which non-protein constituents called co- factors are bound to the the enzyme to make the enzyme catalytically active. In these instances, the protein portion of the enzymes is called the apoenzyme. Three kinds of cofactors may be identified: prosthetic groups, co-enzymes and metal ions.
