During electron transfer an electron is accepted by an iron atom in the pigment portion of a cytochrome molecule which thus is reduced. A cofactor is a non-protein chemical compound or metallic ion that is required for an enzymes activity as a catalyst a substance that increases the rate of a chemical reaction.
Which of the following is TRUE regarding cofactors. Hexokinase Enolase Glucose 6-P Mn 2. Certain metal ions also acts as co factors such as Zn2 is a cofactor for carboxypeptidase.
