Vedclass · Answer

(C) The catalytic activity of an enzyme is dependent on the presence of non-protein constituents called cofactors. Cofactors are of three types: prosthetic groups,co-enzymes,and metal ions. Prosthetic groups are organic compounds that are distinguished from other cofactors in that they are tightly bound to the apoenzyme (the protein portion of the enzyme). For example,in peroxidase and catalase,which catalyze the breakdown of hydrogen peroxide to water and oxygen,heme is the prosthetic group and it is a part of the active site of the enzyme.

What are organic compounds called when they are tightly bound to the apoenzyme?
