Several of the molecules called vitamins act as enzyme cofactors.Vitamin deficiencies cause disease.What is the most direct explanation for this?
A)Vitamins combine with nonprotein molecules to delay the onset of disease.
B)If cofactors are missing,enzymes cannot function properly,and important reaction products will be absent from cells.
C)Normal regulation cannot occur in the absence of cofactors.As a result,all enzymes will function all of the time.
D)Cofactors inhibit enzymes found in disease-causing bacteria and viruses.When cofactors are absent,these disease-causing agents multiply.

Enzymes require cofactors to function properly. If these cofactors are missing, enzymes cannot catalyze important reactions in cells, leading to disease. Vitamin deficiencies cause disease because many vitamins act as enzyme cofactors, and a lack of these cofactors leads to enzyme dysfunction.
