Question

Which of the following can be cofactors? organic molecules,  inorganic molecules,  anions,  cations

Answer 1

I'm answering this super late, but the correct options are: organic molecules and cations

Answer 2

Many enzymes exhibit the catalytic activity only in the presence of certain non-protein substances called co-factors.

They can be organic compounds such as haem in peroxidase and other example includes NAD and NADP.

Certain metal ions also acts as co factors such as Zn+2 is a cofactor for carboxypeptidase.

Thus the answer is organic molecule and cations.
