This is what the notes say:

 

 

COFACTORS *****



  •          Non-protein molecules that are necessary for enzyme action. Tow main groups

  •          COENZYMES - may be metal ions such as Mn2+ or Zn2+ or or complex organic molecules such as NAD+, NADP+, FAD and Flavine mononucleotide (FMN) - they are non-covalently bound to the enzyme

  •          PROSTHETIC GROUPS - are covalently bound to the enzyme at its active site and include metal ions and organic molecules such as biotin
