Answer:

Vitamins work with enzymes to initiate chemical reaction within cells

Explanation:

Sometimes, an enzyme requires for its function the presence of non-protein substances that collaborate in catalysis: cofactors. The cofactors can be inorganic ions such as Fe ++, Mg ++, Mn ++, Zn ++. Almost a third of known enzymes require cofactors. When the cofactor is an organic molecule it is called coenzyme.<u> Many of these coenzymes are synthesized from vitamins</u>. In the lower figure we can see a hemoglobin molecule (protein that carries oxygen) and its coenzyme (the heme group). When cofactors and coenzymes are covalently bound to the enzyme they are called prosthetic groups. The catalytically active form of the enzyme, that is, the enzyme linked to its prosthetic group, is called holoenzyme. The protein part of a holoenzyme (inactive) is called apoenzyme .
