What are the three kinds of cofactors in enzymes?
Options
- AOrganic compounds, proteins, and metal ions.
- BProsthetic groups, co-enzymes, and organic compounds.
- CProsthetic groups, co-enzymes, and metal ions.
- DProteins, co-enzymes, and metal ions.
Correct answer
C. Prosthetic groups, co-enzymes, and metal ions.
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 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.
