Waɗannan cofactors suna da dalilai da yawa; alal misali, ions na ƙarfe na iya taimakawa wajen daidaita nau'ikan nucleophilic a cikin wurin aiki. Cofactors na iya zama ko dai coenzymes, waɗanda aka saki daga wurin aiki na enzyme yayin aikin, ko ƙungiyoyin prosthetic, waɗanda ke da alaƙa da enzyme. Ƙungiyoyin prosthetic na Organic na iya zama covalently (misali, a cikin enzymes kamar carboxylase biotin). Misali na enzyme wanda ke ƙunshe da cofactor na hydroquinolysis, wanda ke da alaƙa da mahaɗan carbon (misali, flavin da heme). Waɗannan cofactors suna da dalilai da yawa; alal misali, ions na ƙarfe na iya taimakawa wajen daidaita nau'ikan nucleophilic a cikin wurin aiki.
