Question

question 29
a type of cofactor would be
a metallic ions
b ribozymes
c active sites
d vitamins
e substrates

Explanation:

Cofactors are non - protein chemical compounds that are required for the protein's biological activity. Metallic ions (such as \(Zn^{2 +}\), \(Mg^{2+}\) etc.) are a type of cofactor. Ribozymes are RNA molecules with catalytic activity. Active sites are regions on an enzyme where the substrate binds. Vitamins (in the form of coenzymes) are also related to enzyme function but are not the same as the general category of metallic ions as a basic type of cofactor. Substrates are the molecules upon which an enzyme acts.

Answer:

A. metallic ions
