Final answer:
Cofactors (inorganic ions) and coenzymes (organic helper molecules derived from vitamins) are essential for the proper function of enzymes.
Step-by-step explanation:
The organic molecules that help enzymes work correctly are known as cofactors and coenzymes. Cofactors are inorganic ions required for the optimal activity of enzymes. In contrast, coenzymes are organic helper molecules, commonly derived from vitamins, that assist the enzyme in performing its action. For instance, the enzyme DNA polymerase requires a zinc ion (Zn2+) as a cofactor to function properly. Similarly, vitamin C acts as a coenzyme for enzymes that synthesize collagen, an essential component of connective tissue.
