- ANAD
- BNADP
- CFAD
- DATP

Answer
- ATP
Explanation:
Many enzymes consists of a protein and non-protein component, they are called as holoenzymes. The protein component of a holoenzyme is called as apoenzyme and the non-protein component may be inorganic ions such as Mg2+ and Mn2+.
They are tightly attached to apoenzyme, they are called as activators. The non-protein components may be organic substances such as NAD+, NADP+ and FAD+. They are loosely attached to the apoenzyme. They are called coenzyme or cofactors.
