Question

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

Explanation:

Cofactors are non - protein chemical compounds that are required for the protein's biological activity. They can be inorganic ions (such as cations like \(Mg^{2 +}\), \(Fe^{2+}\) etc.) or organic molecules (such as coenzymes which are derived from vitamins). Anions can also act as cofactors in some cases. Inorganic molecules (when we consider simple inorganic ions) can also be cofactors.

Answer:

All of the options (organic molecules, inorganic molecules, anions, cations) can be cofactors.
