Choose the option that does not accurately describe the characteristics of enzyme catalase.
The cofactor exhibits an inorganic and proteinaceous nature.
Haem serves as the necessary prosthetic group for the enzyme.
The cofactor necessary for optimal activity must be firmly bound to the apoenzyme.
It facilitates the decomposition of hydrogen peroxide into water and oxygen.
Answers (1)
Option 1 does not accurately describe the characteristics of enzyme catalase. While catalase does require a cofactor for its activity, the cofactor is not both inorganic and proteinaceous in nature. In fact, the cofactor for catalase is a heme group, which is an iron-containing prosthetic group. The heme group is essential for catalase's function in facilitating the decomposition of hydrogen peroxide into water and oxygen.
Hence, the correct answer is option 1.
