Answer
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 $\ce{Mg^{2+}}$ and $\ce{Mn^{2+}}.$
They are tightly attached to apoenzyme, they are called as activators.
The non$-$protein components may be organic substances such as $\ce{NAD_+, NADP_+}$ and $\ce{FAD_+}.$
They are loosely attached to the apoenzyme.
They are called coenzyme or cofactors.
